You all should remember 3 things.
#1 Pre-1996 when the cap virtually had no or little affect on the waiting time...that is, there were visas available for asylees to use and adjust..however at that time, INS took 3 years to process a GC application...in other words, it took 3 years to get your GC and 4 more years to get your Citizenship. So even if USCIS follows the same procedure, a person filling in 2005 would get his GC in 2008.. but remember the backlog may add additional 1 year to the wait..Then they had no backlog in asylee cases.
#2 REfugee adjustments are at 01/2003 state as of now..almost 2.5 years wait..with months passing by, it may turn out to be 3 year total wait. I used to remember few years back in checking I-485's date for Refugees and it was alwasys 3 years....Same for employment cases. So I would assume..Without cap..in the end, the average wait time for any I-485 regardless of
adjustment type would be 3 years...
#3 During the lawsuit fight, USCIS simply said NO they will not adjust 31,000 cases in one year..they have no resources...They agreed to 18,000 so it really means that they will NOT adjust more than 18,000 this year and next year no matter if there is a cap or not...
USCIS should try to catch up with I-485(employment,refugees) for asylee cases in my opinion but it wont happen.
In the end, the lawsuit is good for 2001 or less cases while NO cap is good for anyone filing in 2002 or later. If asylee lawsuit goes throw, its a win-win for every asylee who is in this situation...
