What were some notable differences between H-1B before and after the fee?

The main changes are that U.S. employers could sponsor those who were outside the U.S. or ineligible to change status or change employers in the U.S. without incurring this fee.

Did the number of applicants go down/approval rate go up as a consequence?

		I believe the numbers of H-1B filings has gone down although the H-1B approval rate - so far - seems unchanged.
