Inquiry Submission By carapxn

Hello guys! 🙂 My friend is supposedly going to Cambodia last month for an important business travel. He didn’t have a return ticket at first but we have to do it last minute at the airport hoping they will allow him to board. He was denied by immigration saying his money was too small, he had US$1000 in cash. How can we make sure that the next time he will not be denied? Thank you guys for your help! 🙂
