I m doing my undergrad now in biological science. And i am planning to go for 29 months OPT and than join MPA Pragram. PA program is quite competitive and is two years program. I dont think its that expensive. However, 60-70 thousand will be enough for the program. But after u get your degree, starting pay is like 85K, but it depends on the state too.  So its kinda lucrative field to those whose dream is to be a doctor.

There are some colleges with Undergrad PA program and some colleges with 5 years program. I think its very hard to international students.

So goodluck guys.
