Hello sojhomanchea,
I am not sure in which state you would like to join PA program... But regarding my college, they do have PA program. You may not like my college coz its small but I really enjoy being here.  I am also concerned becz u r already senior in BSC, why do u want to spend 5 more yrs getting PA program. I am not into PA program, but I know getting into PA program is tough. If you would like to get more information then I can give you my college's infomation and international student advisor's contact info.
