My question is regarding to the re-entry
Currently I am out of Thailand and my re-entry date stamp is on 26 September 2022 Due to some emergency I can’t return on 26 is there any problem from immigration if I return after 26?
Thank you in advance 
TLDR : Answer Summary
If you do not return to Thailand by your re-entry date of September 26, 2022, your current visa or extension of stay will become invalid. There is no flexibility with re-entry permits; missing the date means you may lose your right to stay and work in Thailand. It's advisable to consult your employer if you hold a work visa, and consider applying for a new visa, such as an ED visa, from your home country.
