Question about joining frat as an international student

[questionz1]

Going to graduate in my early 20s from a technical school, had to put my social life aside and just focus on difficult science courses all day long.
Want to study abroad for a year abroad and get the chance to study some liberal arts and get a 'proper' university experience since I feel like I'm missing out. If I ended up in the states, would it be possible to get into a nice frat or do I have too many things working against me? Also, is being a full-time student a requirement? Thanks
