Need an advise:
My Indian friend’s mom extended her dependent visa at Korat immigration. Due to missing of an original Birth Certificate, immigration officer stamped on passport without a signature. The immigration officer asked to come back for the signature with the original certificate. The immigration officer didn’t mention when to come back though.
Is there any deadline for such cases? Or can she go back anytime before the next extension?
FYI. Original certificate is being shipped from India.
Thank you.
