I lost my 90 days report card, what's the procedure to follow in order to be able to do a 90 days report at Chaengwattana?
TLDR : Answer Summary
If you have lost your 90-day report card in Thailand, you need to submit a new report at the Chaengwattana immigration office. Typically, you may need to explain the loss, provide identification and perhaps complete a declaration form, so it's important to prepare the necessary documents before your visit.
