This is what I found in the INS web site:
Q13: When will the Implementing regulation be published?
A13: INS is currently drafting the regulation. Because of the new $1,000 fee increase, it is possible that in addition to the normal DOJ and OMB review, this regulation will have to undergo the additional review required by the Small Business Regulatory Enforcement Fairness Act of 1996. If this is the case it is unlikely that the regulation will be published before March 2001. INS is exploring ways to expedite publication of the regulation.
