What are the tips and experiences shared regarding the Long-Term Resident (LTR) visa process in Thailand?

Best visa hands down. Make sure you familiarize yourself with the locations of Fast Track for departures and arrivals at Suvarnabhumi. I always find they get confused when I tell them DTV, so I just say BOI with the page opened in my passport (if you're getting the stamp in your passport).

Also account for an extra 10-15 minutes if entering any border other than BKK, DMK or HKT airport. The officers will look at the visa and scratch their head before calling over a superior.

Finally, if you don't already have a Thai bank account, make sure you go onto the BOI LTR website as they have assistance for opening bank accounts.
