My yearly retirement extension is due mid way thru September.

Last time I did my 90 day report the Kalasin Immigration Officer said to come in August to complete the extension.

How many weeks or month can I complete my extension before my extension due date?

Thank you.

Typically 30 days, 45 in cm.

Extensions can be obtained 30 days prior to expiry at most immigration offices.

45 at some such as CW, CM, Phuket etc.

Recommended to do it min 2 weeks prior

Going to depend what method you use, lump or income. If income, then good advice, do it early, especially if a Yank on Soc Sec..

Lump, if a paperwork oops, you can file again, same or next day. If income, bank might take a week or more to provide paperwork, depending on bank.
