I submitted my only 90 report last Friday, the due date is January 1st, and immigration is closed until 3rd I believe. If I don't get my 80 report confirmed by this Friday will I get fined or is there a grace period because of the holidays?
TLDR : Answer Summary
The 90-day reporting window for immigration in Thailand allows submissions from 15 days before to 7 days after the due date. Despite the New Year holidays, fines will not be incurred if the report is submitted by January 7, as immigration offices will reopen on January 2.
