I am just at the start of the process to apply for me and my wife's LTR visa under the "retiree over 50yrs with >= $80000 annual income" category and ran into a few challenges on the Thai embassy's website here in the US.

I filled out the online application but at the end it wanted me to upload an Authotizatioj letter from BOI (the Thailand Boatd of Investment).

So then I logged into their website and they want me to upload a bunch of documents some of which are mentioned as (To be requested on a case by case basis) e.g., the police clearance certificates.

My question is if i don't submit these in the first go, will they reject my application? Or shall I submit the FBI clearance asking with the rest of it?

Has anyone actually successful been through the LTR process?

I'm in Cakifornia and trying to do this all online before we fly in sometime in late October 2025.

Any advice will be appreciated
