According to the USCIS, the USCIS is to propose to terminate current concurrent I-140 and I-485 filing. The proposed rule is scheduled to be published in March 2007 with 60-day comment period. It is thus not imminent, but in the later part of this year, the immigrant community may see a totally different filing procedure about I-485. Once the concurrent filing is terminated, the immigrants may experience a terrible pain as related to maintenance of nonimmigrant status on pending I-140 petition, eligibility for 245K benefit, plus unavailability of EAD and AP on pending I-140 petition, AC-21 180-day portability, and etc. The best response to this proposal is to file your case as soon as possible. We will keep you posted on the latest updates on this regard.
