labor substitution is legal ONLY IF
1. the offer is genuine - job role, qualification, location, salary etc
2. there is no i-140/i-485 pending/approved based on that labor
3. NOT PAYING MONEY - bribe
since early 2004 you have been trying to find consulting firms who will help you to file labor from suspectible (virtual office) places like wyoming, montana etc. did you find atleast one job similar to your profile atleast once every consecutive month from such states.
people use to bribe 15k prior visa bulletin. looking at the dates now then assume you pay 50k or 100k for preapproved labor and then file i140. if everybody do the same what will happen to your case. current dates will go back again. will you then look for another labor prior to 1994 and then pay 200k or just appreciate people who can afford to pay 200k for 1994 labor & wait in line or realize the mistake.
i am not saying that you should not use preapproved labor. if get a labor then consider yourself as luckiest person on earth and use it to your advantage ONLY if you dont bribe and if the offer is genuine.
if you still insists that paying bribe for preapproved labor is legal and its the smart way then there is no point in trying to explain things to you.
current visa bulletin dates indicates that uscis/dol had to go back on approved cases for possible frauds. more trouble for virtual office and bogus preapproved labor scam users.
