What should I know about switching to the Non-Immigrant O Marriage Visa for expats in Thailand?

Hi everyone!

I’m planning to switch to the Non-Immigrant O Marriage Visa soon as I am now married to a Thai citizen with a child.

I’ll be canceling my current visa, then apply for the initial 90-day visa out of the country.

Since I don’t want to be away from my wife and child for too long, I’m trying to ensure everything is prepared and that the process is as smooth as possible. I have some questions I’d love your advice on if you’ve been through this recently:

1️⃣ E-Visa Process: Has anyone recently applied for the 90-Day Non-Immigrant O Visa through the new e-visa process? Any tips?

2️⃣ Country Choice: Should I go to Vietnam, Lao, or Cambodia to apply? Which is more efficient or hassle-free? The embassy in Vientiane says about 10 to 15 days while Ho Chi Minh City says only 5.

3️⃣ Address Details: Should I list the hotel address where I’ll stay in the country I apply in, the Thai house I’m renting, or my home country address?

Should I add my Thai home or home country as a permanent address option?

4️⃣ Intended Departure Date: Should I put the date 3 months from arrival or a year out?

5️⃣ Accommodation Type: I rent a house—should I select “Guesthouse” or “Private Property”?

6️⃣ Financial Evidence: Will an online bank statement from ibanking.bangkokbank.com work? Or should I get the bank to print it out and then scan it for upload?

7️⃣ Proof of Relationship: When I was going to apply in person they asked for a copy of the Kor. 2 from the local office, so do I need that as well or just upload my child's Thai birth certificate and original Thai marriage cert.?

When applying in person, they asked for additional documents like maps, photos of us at home, and house registration. Do I need anything else like that?

Any advice, experiences, or tips would be greatly appreciated! Thank you.
