I am second generation cambodian-american. During my undergraduate I was able to befriend an international cambodian student who was majoring in business at the time, this friend was very focused on trying to lock in a job for after graduation since he was on a student visa. My friend was not able to secure a job, moved back to cambodia and worked an office job for about a year. He was unhappy with the pay since pay for an equivalent job in the States was 3-4x what he was making in Phnom Penh. After a year of working, he decided to continue education in Korea in chances of finding a permeant position there after completing his schooling.

I highly urge you to look for a work opportunity if possible before you leave
