Landing on Saturday with a OM visa never done the notification of been out of the country before. I know before this forum said do not think about it since i never visit immigration an leave every 3 month but this time i need a permit for drone and they need a residence document from Immigration.

What document do i need for the two of them? Can i go to Pattaya immigration on Monday even if i land on Saturday not 24 hours?

Thank you sorry if i did not use the correct words.
