I assume this is okay to do but I need to be sure....

I have a double entry 60 day tourist visa. I entered the country by air for the first visa....actually I always have come by air into Thailand.....

I then got a 30 day extension here in BKK. Soon I need to leave and re-enter to get the next 60 days.

I would like to go to Angkor Wat by land. I will return to Thailand by land also. I assume I still can get the new 60 days if I enter Thailand by Land...Is that correct?

Thanks so much for your help.

Yes, you can use your visa to activate the second entry at any border immigration point, arriving by land or air, as long as the visa itself is still valid on your arrival.

As said above, no problem as long as the Visa is still valid.

Thanks!
