I am an Indian passport holder going to Bangkok directly with Single entry visa on 1st October. Then I will go to Cambodia for 3 days and again will return back to Bangkok on 7th through Flight to BKK airport. Now, what is my options?
1. Can I take a re-entry permit from Immigration Office in Chaengwatthana before my travel to Cambodia?
2. I go out from Bangkok on 3rd to Cambodia and return back to BKK airport on 7th and go for a Visa on arrival?
