I was on an 1 year extension based on a marriage visa from 2019. However I left Thailand to go back to the UK at the end of 2021 I think I had about 3 months left, but I decided I'd just get another married visa and start the process again when I returned. so I came back to Thailand in January and then later applied for an extension based on having a Thai wife. Everything seemed to go smoothly and I checked my passport and all the dates were correct, so I left immigration. However when I got home I noticed that instead of putting in the small bit of paper that tells you your next 90 day report, they'd put in one from the previous visa. I didn't think this was an issue but I've just tried to get a resident letter at immigration today so I can get a driving license and they said I need that bit of paper that says when my next 90 day report should be and as I don't have it they can't give me the resident letter and also told me I need to go to the police and tell them I've lost the bit of paper before I do my 90 days. I would like a driving license but I am kind of stumped, I guess I have to go to a police station and get a report then wait 2.5 months until my 90 days before I apply for a driving license.
TLDR : Answer Summary
The user returned to Thailand after a trip and applied for a visa extension based on marriage. Upon checking, they discovered they received an old 90-day report slip instead of a new one for their current extension. Now, they need that slip to obtain a residence certificate for a driving license, but don't have it. Comments suggest that the user should ask for a 90-day report instead of the residency certificate, as it's possible to get the correct slip printed out. They also clarified that the absence of the report doesn't constitute a loss, and they may need to check their immigration status based on the last entry stamp.
