For international doctors, the process to obtain visas to practice in the United States is riddled with backlog. The problem is ever-present in rural Minnesota — where some areas are facing a shortage in primary-care physicians.

It's why Sen. Amy Klobuchar and Rep. Tom Emmer have introduced legislation to ease the backlog and help doctor shortages in rural areas.

Klobuchar's legislation, the Conrad State 30 & Physician Access Act, would expand the Conrad 30 program, which allows 30 doctors from each state to stay in the U.S. (instead of having to leave and apply for another visa or green card) if they practice in a shortage area for three years. It would make Conrad 30 permanent — it's set to expire on Sept. 30.
