How Do I Bring My Fiancé to the United States?
A U.S. citizen engaged to a Thai partner who wants to marry and live in America typically uses the K-1 fiancé(e) visa, not a tourist visa. The B-2 visitor visa is for temporary trips; using it to immigrate can result in denial and long-term bars.
Thai Visa Centre helps couples with marriage registration in Thailand and coordinates U.S. visa document preparation from our Bangkok office. This FAQ explains the K-1 pathway in plain terms.

Short answer
The K-1 visa lets a Thai fiancé(e) enter the United States once for the purpose of marrying the U.S. citizen petitioner within 90 days of arrival. After marriage, the Thai spouse applies for Adjustment of Status (AOS) to become a lawful permanent resident (green card).

Key eligibility requirements
Both partners must meet strict rules:
- Petitioner must be a U.S. citizen (green card holders use different routes: CR-1/IR-1 spouse visa)
- Free to marry. Both legally single; prior divorces documented
- Met in person within the past two years (limited waiver available in hardship cases)
- Genuine intent to marry within 90 days of U.S. entry
- Financial support. Petitioner meets minimum income or uses a joint sponsor (Form I-864)
- Thai partner passes medical exam and police certificates as required
After the K-1 arrives in the United States
- Marry within 90 days. Missing this deadline violates visa terms
- File I-485 Adjustment of Status with supporting documents
- Apply for Employment Authorisation Document (EAD) and Advance Parole if needed while pending
- Attend AOS interview if required
- Receive conditional green card. May later remove conditions (I-751) if marriage is under two years at approval
Alternative: CR-1/IR-1 spouse visa
If you marry first. Including legal registration in Thailand. You may skip K-1 and petition for a CR-1 or IR-1 immigrant spouse visa. The Thai spouse enters as a permanent resident. Many couples already married in Thailand choose this route.

Before you travel or file
Use this checklist alongside the steps above. Most rejections we see at Bangkok immigration come from missing one item on this list rather than from the main visa rule itself.
- Download the current checklist from thaievisa.go.th for your nationality and visa category. Lists change without wide announcement.
- Complete TDAC within 72 hours before every flight, train, or land crossing into Thailand.
- Carry printed copies of embassy letters, insurance certificates, and financial proof, not phone screenshots alone.
- Confirm your passport has enough blank pages and validity for the full intended stay plus buffer days.
- Book embassy or district office appointments before you fly if your nationality requires in-country processing in Bangkok.
- Set calendar reminders for 90-day reporting, extension expiry, and re-entry permit dates before you leave on holiday.
Who this guide is for
This FAQ is written for foreign nationals planning travel, registration, or long-stay compliance in Thailand. The answer may differ if you hold a Thai passport, diplomatic status, or a work permit tied to a BOI-promoted company.
Short-stay tourists
Verify visa exemption or VOA eligibility, complete TDAC, and carry travel insurance even when not mandatory. Hospitals expect payment or cover before major treatment.
Long-stay visa holders
Track TM30, 90-day reporting, annual extensions, and re-entry permits. Privilege and LTR tiers may simplify some reporting but never remove TDAC or overstay rules.
Couples and families
Marriage registration at a district office is separate from ceremonies and from marriage visa applications afterward. Plan embassy documents and MFA legalisation before you book wedding venues.
Workers and employers
A B visa alone does not authorise work. Every employer change requires a new work permit. Remote work for foreign employers on tourist stamps remains high risk at immigration.
Compliance reminders
Thailand is welcoming when your paperwork matches your behaviour. These habits apply across most visa categories, whether you are visiting for two weeks or renewing a one-year marriage extension.
- Complete TDAC within 72 hours of every landing, including returns after holidays abroad.
- Confirm your landlord or hotel files TM30 address notification within 24 hours of check-in.
- File 90-day TM47 reports when you remain in Thailand 90 consecutive days without departing.
- Obtain a re-entry permit before leaving if you hold a single-entry visa with a valid extension.
- Match your visa category to your activity. Tourism stamps do not authorise employment in Thailand.
Common mistakes
These wrong assumptions appear frequently at our Bangkok office. Correct them before you book non-refundable flights or sign a lease.
- Relying on outdated forum advice instead of current official lists.
- Arriving without TDAC completed before landing.
- Mixing tourist entry with work or long-stay plans without the correct visa.
- Missing translation or MFA legalisation on foreign documents.
- Assuming a ceremony or stamp alone creates legal status without registration or extension.
