TLDR : Answer Summary

The user inquires about the timing for applying for a marriage visa (Non-O) before arriving in Thailand and whether to purchase a reentry permit upon arrival or during the visa application process. Several community members suggest applying for the Non-O visa up to 90 days prior to arrival, with a recommendation to start the process 45 days ahead of the trip. It is clarified that if the user does not plan to leave Thailand within the first 90 days, they should wait until they obtain a one-year extension to purchase the reentry permit. Additionally, advice is provided about opening a Thai bank account and preparing for an extension application after the initial 90 days.

I'll probably be criticised for this, but getting a Non O based on retirement makes you totally independent. That's of course if you meet the requirements.

What do you mean "fill out your marriage visa"? Do you mean when should you apply through an embassy for the Non-O based on marriage? Once it's issued it's valid for 90 days for you to enter. They will then stamp you in.

Up to 90 days before arrival, it is single entry and gives you 90 days inside Thailand. On arrival you should open a Thai bank account and deposit a minimum of 400k baht. 30 days before your stamp runs out go into your local immigration office and get the list of requirements for a 1 year extension

Your questions do not make sense. I assume that you are currently outside of Thailand ans married to a Thai lady. Do you have a Thai bank account? If not you need to arrive in Thailand on a long term visa. That is because you cannot open a bank account here on a tourist visa. A reentry stamp is obtained at an Immigration office inside Thailand or at a departure airport.

A Non-O visa is valid for 90 days from the day it is issued. So you can start anytime within 90 days of your trip. Generally 45 days is plenty of time.

Are you planning on leaving Thailand within your first 90 days? If not, then you don't need a re-entry permit. Wait until you get the 1-year extension to buy the re-entry permit, because they are only valid until the end of the stamp you purchase them for.

So you currently do not have a Non-O?

If so, you go apply for the Non-O based on marriage to Thai citizen here
