my mates son from uk,is on a world back packing tour,in cambodia at the moment,wants to stay at least two months in los,is it okay he gets his 15 days at land border post cambodia,come to cnx get a thirty day extention,then go and do a visa run to mai sai for another 15 days,would appreciate reply and subject,cheers.

The longest extension he get for a 15 day visa exempt entry is 7 days.

The 30 day extension is for tourist visas only.

He could get a single entry tourist visa in Cambodia that would give him a 60 day entry.
