In short, it doesn’t practically prevent future H1B fraud from ICCs, and we should expect a more competitive H1B lottery in 2016: these extra $4000 for preventing multi-filing fraud will only be conducted AFTER the lottery, thus, a visa cheater can still submit multiple H1B petitions and later on send 4000$ check to USCIS after being selected in the lottery for fixing the RFE. What a perfect loophole for H1B fraud!

We don`t think there will be any effect on H-1B filings this year since the fee is only deducted after getting selected in the lottery. We can still expect a lottery this year.
