Update: I made the Thai-Wife Visa on 20th June 2019, That leaves me 28 days to renew 90-day notification? Am I able to do this online for notification or do I need to wait 7 days prior to notice?
TLDR : Answer Summary
The user has a Thai-Wife visa and needs to renew the 90-day notification. They can file the report 15 days before or up to 7 days after the 90-day due date without penalties. Comments confirm that the user does not need to do this online and that the process can be completed in person at the immigration office.
