yes. I had their list of requirements that I picked up at least a month in advance. Then went there with all my documents. A lady reviewed them and then gave me an appointment for the following week. Not mentioning any of the "missing" documents.

When I went for my appointment they required at least 3 or 4 more documents that were not on the list and not required by any other office I've used for previous extensions. One was a document they wanted from my landlord, who did not want to give them it. He is Thai and has a couple dozen rentals and has never needed to supply it before. He was quite upset and even called immigration to complain. So it took running around to a few different government agencies to get documents they would accept instead. Plus another 2-3 trips to immigration.

Definitely talk to your immigration office and don't wait. It should be more than enough time, but there are some offices that make it difficult and more time consuming. It took me almost 2 weeks to get my last one, and I've been doing extensions for years now.

This last one was at a new office and they wanted additional documents no other office needed and had to have an appointment every time I went back. I think I got my 30 day extension the day my previous stamp expired.

@Adam ******

not necessarily. I filed my first report online after leaving the country and obtaining a new extension in a new province. Never hurts to try online first since you can apply 2 weeks prior.

What did you provide the firm as examples before they hired you?

that video is referring to those that enter on something other than a long term visa, like a visa exempt or tourist visa, and want to convert in country. That is a completely different ball game than obtaining a 90 day non-o prior to entering thailand. For those that get the non-o based on marriage there isn't really any other option.

I would check with the immigration office you plan on using as far as the last day you can apply. I went about 2 weeks prior to my current expiration and they were not too happy about it. They said next time come 4 weeks before. Even with 2 weeks I barely got the application finished since they wanted a bunch of extra documents from my landlord that he was not willing to give.

You may want to double check your policy. Typically the emergency coverage worldwide has quite a few limitations, including duration of coverage. Many will only cover for 60 to 90 days of international travel.

@Sujy ********

you dont have cancel a non-o visa or non-o extension, as long as you don't have a reentry permit. Simply leaving the country will cancel the permitted to stay stamp. I've done this before intentionally to start over so my renewal date would line up at a more convenient time of the year for me.

@Rok *******

good question, not sure how that part works. I could see that being an issue if one just went to immigration to start over vs bouncing out to a neighboring country and applying for the non-o while there.

I think when most people talk about it being difficult to switch from an agent to DIY all it means is you will unlikely be able to simply apply for another extension since the agent got you around the financial requirement. When you go to get your new extension you will need to prove you fulfilled the requirements of the last one. You will need to show that the 800k remained in your account for 3 months after you got your last extension and it didn't go below 400k the rest of the year. If you can't provide the documents to show that, then you will have to start over.
