Business Investment Visas in Southeast Asia in 2026

Business investment visas in Southeast Asia do not work as one simple option. In Thailand, Vietnam, Cambodia, and the Philippines, a foreign-owned or foreign-invested business supports a long stay only if the company structure, work permission, capital or staffing proof, and ownership rules all line up. The cheapest-looking path is not always the safest one for someone running a cafe, shop, restaurant, English center, trading company, or startup.

This guide is for foreigners who want to own and operate a real business, not buy a passive golden visa or a retirement deposit. It covers Thailand, Vietnam, Cambodia, and the Philippines. Indonesia and Laos are not included.

Business stay options for foreign owners in four countries

This guide reflects business and investor visa rules for foreign company owners as understood in June 2026. Requirements can change without advance notice. Verify current requirements directly with each country's immigration authority and company registrar before proceeding.

Who this guide is for

You are running, or planning to run, a working business and you need that business to keep you in the country legally. Common cases are a foreign founder opening a cafe, shop, English center, or trading company, and a foreign spouse who helps run a family business.

The four countries treat this very differently. Vietnam ties your visa class directly to how much capital you put in. Cambodia keeps the business stay flexible but paperwork-heavy, with the EB extension and work permit details best confirmed locally. Thailand separates the company, the visa, and the work permit into three files. The Philippines offers an investor visa, an employment-generation visa, and a standard work visa, each with its own test.

What business investment visas in Southeast Asia actually get you

Four separate things have to line up, and no single document covers all of them.

• A visa or stay basis. This is your right to be in the country. In Thailand the Non-B visa is the entry and stay basis, and it does not by itself allow you to work.
• Work permission. Running your own business usually counts as work. In Thailand a work permit must be granted before you start working. In the Philippines, working requires an Alien Employment Permit from the Department of Labor and Employment. In Cambodia a work permit is mandatory even for an owner.
• Company ownership. Whether you can hold 100% depends on the country and the sector. Cambodia and Vietnam allow full foreign ownership in most ordinary businesses. Thailand and the Philippines restrict it in many domestic sectors.
• A stay document or card. Vietnam can issue a Temporary Residence Card. The Philippines issues an ACR I-Card. Thailand runs on stay extensions tied to the work permit rather than a normal residence card.

Read every country offer against these four points. A visa that lets you live in the country is not the same as one that lets you legally work in your own shop.

Thailand: company, work permit, and the nominee risk

Thailand's Foreign Business Act caps foreign shareholding at 49% in restricted activities unless an exemption applies, according to practitioner analysis of the Act. Most service, retail, and hospitality businesses sit on List 3, which a foreigner can enter only with a Foreign Business License. Three exemptions allow more control. A Board of Investment promotion can grant up to 100% foreign ownership, but it is a sector-specific exception, not the normal path for a cafe, small shop, ordinary restaurant, or small trading business. A Foreign Business License permits foreign-majority ownership in some List 2 and List 3 activities. The US Treaty of Amity lets American citizens hold 100% in most sectors, excluding land, communications, and natural resources.

Most foreign-owned Thai businesses need paid-up capital of at least THB 2 million, rising with the type of business and the number of foreign work permits requested.

The visa and the work permit are separate. The Non-B visa is the stay basis and does not allow work on its own. A work permit must be granted before you start working, supported by corporate documents such as the company's business registration, shareholder list, company profile, foreign-worker list, office map, and tax and VAT records. Two overlapping checks then apply. The Department of Employment ties work-permit issuance to about THB 2 million of paid-up capital per foreign worker, halved to THB 1 million for a foreigner married to a Thai national. Immigration Bureau business-extension rules separately require paid-up capital of at least THB 2 million and roughly one foreign employee for every four permanent Thai employees, with exemptions for representative, regional, and branch offices.

The bigger 2026 issue is enforcement against nominee shareholders. The Department of Business Development has intensified review of companies suspected of using Thai nationals as proxy holders, with focus on tourist and business areas, according to practitioner reporting. A 51% Thai shareholding is not automatically compliant. Regulators look at who funded the shares, who controls the bank accounts, and who takes the profit. Penalties can include imprisonment of up to three years, fines up to THB 1 million, forced closure, asset seizure, and cancellation of visas or work permits.

Thai labour rules also shape running costs. Probation can run up to 119 days. An employee who completes 120 days of continuous service becomes entitled to statutory severance, and a dismissal without gross misconduct after that point owes one month's wages, with 30 days of notice.

Vietnam: the DT investor visa and 100% ownership

Vietnam splits the investor (DT) visa into four classes by capital, under Law 51/2019/QH14. DT1 covers capital of at least VND 100 billion and runs up to 5 years. DT2 covers VND 50 billion to under VND 100 billion, also up to 5 years. DT3 covers VND 3 billion to under VND 50 billion, up to 3 years. DT4 covers under VND 3 billion and is valid for up to 12 months.

The class decides what you get. DT1, DT2, and DT3 are listed for Temporary Residence Card eligibility. The card validity is not one flat number. DT1 runs up to 10 years and DT2 up to 5 years, while DT4 is not listed for a TRC. Confirm the current DT3 card validity with immigration before relying on it.

Capital also controls work permission. A foreigner who owns or holds equity in a company with a capital contribution of at least VND 3 billion is exempt from the work permit requirement. Below VND 3 billion, the DT4 holder has no exemption and must obtain a work permit to operate. Treat VND 3 billion as a capability cliff, not a minimum needed to start a business. Below it, a DT4 investor can still register, but should check whether the company can support a separate work permit and whether a 12-month visa with no residence card is enough for the stay they want.

Foreign ownership is open in many ordinary sectors. Practitioner sources report that Vietnam allows 100% foreign ownership in many sectors, including trading, manufacturing, and e-commerce, unless the sector is restricted or conditional. Setting up requires a registered company with a Business Registration Certificate and Investment Registration, a tax number, a local bank account, a criminal record check, and a health check, with filings handled through the current provincial business and investment registration authorities. A DT visa also feeds into the wider set of long-term stay options in Vietnam once the company is running.

Cambodia: flexible business stay, but not paperwork-free

Cambodia’s public embassy guidance confirms a Type-E business visa for business purposes, supported by an invitation from a Cambodian company or a sending-company letter. It is a 30-day entry visa that can be extended after entry. Practitioner sources describe the EB extension as the usual business-stay route for owners, but the extension length, renewal file, and fee should be confirmed locally before publication. A work permit is mandatory if you are working in the business.

Capital figures get confused, so keep the visa and company file separate. Older company-registration references mention KHR 4 million, about USD 1,000, but that is not confirmed as a current official minimum, so check it with the Ministry of Commerce. Treat Cambodia’s company-capital figure as a local-registration check, not a settled visa rule.

The EB does not grant permanent residence by itself. One immigration firm describes a citizenship route after seven years of residence, subject to conditions, which is a practitioner claim rather than a guaranteed outcome. Reachable community reports also describe small foreign vendors facing repeated informal payments to local officials, so a visible street-level business carries practical exposure beyond the paperwork.

Philippines: investment, employment, and ownership limits

The Philippines offers three different long-stay options that are easy to confuse. Read them as separate things.

SIRV: the investment residence option

The Special Investor's Resident Visa lets the holder stay as long as the investment subsists, with a minimum of USD 75,000, according to the Board of Investments. The money must go into eligible investment channels under the SIRV rules, not simply into any small business. BOI materials describe qualifying investments through shares, listed companies, Investment Priorities Plan projects, and qualifying manufacturing or service corporations. A new corporation must fit the permitted categories. SIRV is not a cafe-or-shop visa. It works for an operating business only if the investment is structured as qualifying shares in an eligible company. The holder must keep filing proof of investment, a business or mayor's permit, audited financial statements, BIR registration, and tax returns, and missed filings can lead to fines, non-renewal of the ID card, cancellation of the visa, or blacklisting.

SVEG: the employment-generation option

The Special Visa for Employment Generation is for a foreigner who actually employs at least 10 Filipinos in a lawful and sustainable business, according to the Bureau of Immigration. It grants multiple entry and conditional extended stay, and can extend to a spouse and unmarried children under 18. This fits a foreign owner who runs a genuine team, not a one-person shop.

9(g): an employment visa, not an investment visa

The 9(g) is a pre-arranged employment visa. It supports working for a company, not investing in one, and it is the wrong label for an owner who is funding rather than being hired.

Ownership limits: FIA, retail, and the negative list

The Philippines is not one simple 60/40 market. RA 11647 allows a non-Philippine national to own up to 100% of an enterprise unless foreign participation is prohibited or limited by the Constitution, the Foreign Investment Negative List, or another law. Small domestic-market enterprises with paid-in capital below USD 200,000 are reserved for Philippine nationals. A USD 100,000 threshold can apply if the business uses advanced technology, is an endorsed startup or startup enabler, or has a majority of Filipino direct employees, with at least 15 Filipino employees. Foreign retail is separate. Under RA 11595, a foreign retailer needs at least PHP 25 million in paid-up capital, with an additional per-store capital rule when operating more than one physical store. The full set of Philippine long-stay options shows where each of these fits.

Can you legally work in your own business?

Owning the company is not the same as being allowed to work in it. Each country answers this separately.

In Thailand, the Non-B visa does not permit work by itself. The Ministry of Foreign Affairs says the holder must be granted a work permit before starting work. In the Philippines, working normally requires employment permission such as an Alien Employment Permit. In Cambodia, a work permit is a separate requirement from the EB stay basis, and you need it to work in the business. In Vietnam, the answer turns on capital. A capital contribution of at least VND 3 billion supports the work-permit exemption; below that, a DT4 investor needs a separate work permit.

For a budget-conscious owner, this is where costs hide. The visa fee is rarely the obstacle. The work permit, the Thai staffing and capital tests, and the Vietnamese capital line are what decide whether you can legally stand behind your own counter.

Who controls the company: ownership and nominee risk

Control is the real dividing point between these four countries.

Cambodia and Vietnam allow full foreign ownership of most ordinary businesses, so a foreign owner can hold the shares and the decisions directly. Thailand and the Philippines push many domestic businesses into local-majority structures, which is where the risk starts.

Both countries treat nominee arrangements as illegal. In Thailand, putting Thai shareholders on paper while a foreigner funds and controls everything can trigger criminal penalties, and enforcement is active in tourist and business areas. In the Philippines, a Filipino holding equity on behalf of a foreigner is illegal and increasingly targeted by regulators, according to practitioner analysis. If you cannot legally own the majority and you do not have a genuine, funded local partner, the honest options are a different visa, a different sector that allows full ownership, or a different country.

Which option fits a budget-conscious owner-operator

Start from what you can legally control, then look at capital.

If full ownership of a small operating business matters most, Cambodia and Vietnam are the most direct. Cambodia can look low-cost on entry, but the exact current company-capital figure, EB extension cost, and work-permit cost should be checked locally before treating it as the cheapest option. Vietnam allows 100% ownership in most sectors, but full work rights and a residence card require a capital contribution of at least VND 3 billion. Below that, you are in DT4, with a 12-month visa and a separate work permit.

If you are tied to Thailand or the Philippines, the math changes. Thailand needs THB 2 million in capital and the Thai-staff ratio for a standard work permit, unless you qualify for BOI, an FBL, or the US Treaty of Amity. The Philippines reserves small domestic-market businesses for nationals below USD 200,000 paid-in, and foreign retail starts at PHP 25 million. Neither is a low-capital home for a solo foreign owner in a restricted sector.

Government fees are small next to company setup, licensing, tax, lease, accounting, and legalization. The official charges are:

• Thailand. The Non-B visa is THB 2,000 for a single-entry three-month visa and THB 5,000 for a one-year multiple-entry visa. The work-permit fee should be confirmed against the Department of Employment schedule before publication.
• Vietnam. The work-permit state fee is set by province, for example VND 400,000 in Hanoi and VND 600,000 in Ho Chi Minh City, up to a current high of VND 1,000,000. Immigration fees for visas and residence documents fall under Circular 28/2026/TT-BTC, effective 1 April 2026.
• Cambodia. A Type-E business visa is USD 35 through the Cambodian Embassy in Washington, with 7 to 10 working days listed for embassy processing. EB extension and work-permit fees vary by route and should be confirmed locally before quoting a total.
• Philippines. The Bureau of Immigration lists the SVEG fee at PHP 29,330 for the principal and each listed dependent, plus USD 250 for the SVEG ACR I-Card, but the same page says those fees were updated on 6 March 2014 and may change without prior notice. Treat the SVEG figure as an official published reference, not a current total. Confirm current BI, BOI, DFA, ACR I-Card, and employment-permit charges before filing.

What owners report online, and where the evidence is thin

Community evidence is uneven across the four countries, so weigh it accordingly.

For Thailand it is the strongest. Owners frequently report running businesses through a Thai-spouse-majority company or the US Treaty of Amity, and they describe the Thai-staff and capital tests, agent and nominee risk, and harsh competition in cafes and restaurants. Several long-term owners say the process is manageable once a good accountant is in place.

For Vietnam, reachable discussions lean toward finding a trusted local partner, even though trading and most sectors legally allow full foreign ownership. Treat the partner advice as cultural preference, not a legal requirement.

For Cambodia, reachable community reports raise informal payments and a saturated bar and massage market, and note that company registration itself is quick and online. The sample is small, so read it as direction, not proof.

For the Philippines, owner-operator community evidence is thinner, and the official rules carry more weight. First-hand reports describe ownership limits, strict tax administration, and slow local permits rather than visa mechanics.
