TOO dangerous decision

Compared with IT market, nurse is a small pie: only about 100,000 positions avaible. Thousands of American people are graduating from nursing schools each year. Most probably one or two years later, nurses (especially foreigrn nurses) are not deadly wanted. Then few hospital want sponsor GreenCard when many American nurses are availble. But you have lost both TIME and MONEY. IT or accounting is an advanced skill. How about Nursing?
Don't be so silly.
