Arrival in the US: SFO on Nov 28 (BR018, 15:00) — immigration and customs at SFO, then re-check bags for AS1347 (4h40 connection). Departure from the US: SFO on Dec 11 (BR027, 23:30). Baggage 2 pieces on every segment. Opal (separate ticket booked directly with EVA on Aug 26) is on the same 4 EVA flights, but seats are not together (Kajonsak 22G/22D/21G/— vs Opal 22K/22E/25A/23K) — request adjacent seats. US domestic legs are all booked (Oct 5-6): Nov 28 AS1362 SFO 19:27 → LAS 21:07 (Alaska retimed Kajonsak's AS1347; Opal on a separate Trip.com ticket with TripFlex, so she can cancel for a full refund before departure if BR018 runs late) · Dec 5 Delta DL2678 LAS 13:55 → LAX 15:11 (both) · Dec 8 Alaska AS640 LAX T6 12:43 → SFO T1 14:09 (both). Kajonsak's AS634 LAS→SFO on Dec 5 is no longer used — ask the agency before cancelling. Do not manage the Trip.com bookings on airline websites (it voids TripFlex); pay checked bags at check-in (Delta/Alaska ~ $35-45 per bag).

Status (updated Oct 6, 2026):
0) All US domestic flights booked (Oct 5-6) for both: AS1362 SFO→LAS Nov 28 (19:27), DL2678 LAS→LAX Dec 5 (13:55), AS640 LAX→SFO Dec 8 (12:43). Still open: Kajonsak's unused AS634 (ask the agency), LA/SF hotels.
1) Interview date to verify: 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: active (confirmed Sep 27). Keep the registration confirmation email and check the registration portal again the week before the interview, because the visa letter states the attendee is registered and paid the fee.
Done: DS-160 for both · MRV $370 paid · employment letters · re:Invent visa letter · interview prep sheet (05-Interview-Prep/). Still to collect: Opal DS-160 confirmation, 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).

US Visa (B1/B2) Preparation
Interview: Wed Oct 21, 2026 08:30 (verify vs Oct 26 07:45) · Self-funded, on personal leave · Event: Nov 30 – Dec 4, 2026
1. Document Checklist
Essential Documents (per person)
Supporting — Kajonsak (Primary)
Supporting — Opal (Accompanying Spouse)
Supporting — Financial (both)
Supporting — Ties to Thailand
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 to attend AWS re:Invent 2026 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, personal leave, employer aware and approved the leave. Do not describe the trip as company-sponsored.

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:
- You are attending a specific conference (re:Invent) with fixed dates
- Trip is self-funded; employer approved personal leave; attending for professional development
- 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 your travel purpose (re:Invent) and itinerary
- Emphasize ties to Thailand: her job at True (team lead), home and family in Bangkok
- Be ready to explain: "My husband is attending a technology conference on his leave. I am joining him and we travel back together on Dec 11."
- Bring the Marriage Certificate (original + copy)
- Bring her own employment certificate and, if available, her bank statement
