I am currently pending I-485 (EB3, skilled worker employment based, priority date Oct 2008) since April 2014. I submitted inquiries through congressman, they received a letter that my case is on hold indefinitely. Do you recommend filing Writ of Mandamus or would that cause a denial? What other actions can I take, I've submitted a case through the Ombudsman and met with a USCIS officer through Infopass appointment (who told me nothing). No RFEs have been issued for this case, I-140 was approved and fingerprinting done (twice, since first set expired).

1) Is there any difference between I-140 revoked by employer - vs - I-140 revoked by USCIS (say for fraud or misrepresentation) with respect to being able to retain the priority date with the new employer ?<br>
2) Changing from Employer A to Employer B - If Employer B files the PERM before I-140 by employer A is revoked by the employer A - would that help retain the PD corresponding I-140 to employer A ? In other words, are there any specific scenarios in this case - where the PD could be retained based on the first I-140 approval ?

I am on H-1B visa and in green card process (waiting for I-485 date to become current). I would like to know if I buy and rent houses on my own name (without forming an LLC) and actively manage the activities (finding a renter, maintenance etc) and make profit out of those rentals, then would it violate my status?
