[laraibadil]

I am free member of PRMIA (Professional Risk Managers' International Associations) USA, for last 03 years.

Professional i am Manager Credits/Assistant Vice President in a bank for last 15 years.

The captioned professional body conducts each year professional courses on Credit Risk Management,which last for a few weeks like A Course in Credit Risk Modeling Best Practices: Wednesday Evenings for Three Weeks.

I am confused whether i go for B1/B2 or student visa. I need help for proceeding further.
