Status (updated Sep 27, 2026) — 2 items to confirm first:
1) Interview date: the AppointmentManager page (Sep 22, 11:16) shows Wed Oct 21, 08:30, but the saved confirmation PDF shows Mon Oct 26, 07:45. Log in to ustraveldocs, view only, and download the current confirmation. Do NOT touch Reschedule/Cancel — the reschedule limit is exhausted.
2) re:Invent registration: AWS employees may not buy their own pass, and self-purchased registrations are being cancelled. Until a valid pass is confirmed, the trip is presented as a vacation and the re:Invent visa letter is not used.
Done: DS-160 for both · MRV $370 paid · employment letters · interview prep sheet (05-Interview-Prep/). Still to collect: Opal DS-160 confirmation + e-ticket, marriage certificate, leave approvals, bank statement, LA/SF hotels, $250/person Visa Integrity Fee.
Trip is self-funded, on approved personal leave (DS-160 "Person paying" = Self for Kajonsak, Spouse for Opal).
Use the Visa Prep tab to work through the document checklist — tick items as you gather them and your progress saves automatically on this device. The Travel Guide tab has the LA & SF day-by-day plan and food picks.

Travel Arrangements
2. Employment Verification Letter
Status: obtained (FINAL, Sep 12, 2026) — filed under 01-KT/Employment-Confirmation-AWS-Thailand-KT-2026-09-12-FINAL.pdf. Bring the original printout to the interview.
What the letter states: full-time employment at AWS Thailand (position, start date), that the trip is personal travel on approved leave, and that the applicant will return to resume duties. It does not state that the company sponsors or pays for the trip — this matches the DS-160 (Person paying = Self).
Opal's employer letter (True, Sep 5, 2026) is filed under 02-Opal/. Leave-approval evidence for both is still to be added.
Consistency rule: every document and every spoken answer must say the same thing — self-funded vacation, personal leave, employer approved the leave. Do not describe the trip as company-sponsored, and do not claim a conference registration unless a valid pass is confirmed. The re:Invent visa letter (Aug 13) states "registered, fee paid" — do not submit it unless that is still true.

5. Timeline & Action Items
6. US Embassy Bangkok — Interview Tips
Location: 95 Wireless Road, Lumpini, Pathumwan, Bangkok 10330
- Arrive 30 minutes early for the confirmed slot (Oct 21 08:30 or Oct 26 07:45 — verify) — security line forms early
- No bags or electronics (laptop, tablet, camera, power bank) — the Embassy has no storage. Mobile phones: check the current limit on the ustraveldocs Security Regulations page before the day
- Dress professionally — business casual is fine
- Be concise — answer only what is asked
Key points to emphasize:
- A fixed two-week vacation with your spouse, return ticket booked
- Trip is self-funded; both employers approved personal leave
- You have strong ties to Thailand (both of you employed full-time in Bangkok, home and family here)
- You return to Thailand on Dec 11 (arrive Dec 13) to resume work — travelling and returning together with your spouse
Tips for Wife's Interview
- If interviewing together, the officer may ask her questions separately
- She should know the purpose (vacation together) and the itinerary
- Emphasize ties to Thailand: her job at True (team lead), home and family in Bangkok
- Be ready to explain: "We are going on vacation together. We both took leave from work and we fly back together on Dec 11."
- Bring the Marriage Certificate (original + copy)
- Bring her own employment certificate and, if available, her bank statement
