What you cannot do
These restrictions apply to most US visa categories. Confirm permitted activities for your specific visa type.

Common mistakes
These errors show up repeatedly in our Bangkok consultations for US visa cases.
- Booking US wedding venues before K-1 visa approval
- Using outdated USCIS processing time estimates from forums
- Slow response to USCIS Requests for Evidence extending total wait
- Assuming Embassy Bangkok interview happens immediately after I-129F approval
- Expecting TVC or any consultant to shorten government processing queues
Planning checklist before you travel or relocate
Confirm your entry category, passport validity, and return plans before booking non-refundable flights or long hotel stays. Immigration officers compare your stated purpose with your visa stamp, prior entry history, and supporting documents at the counter.
Register your address through TM30 when required, complete TDAC before every arrival, and keep copies of lease agreements, insurance policies, and embassy correspondence in one folder. These records matter for extensions, tax filings, and unexpected compliance checks.
If your situation involves work, marriage, retirement funds, or property purchase, book a case review with our Bangkok team early. Small document gaps that seem minor at arrival become expensive fixes at extension season.
