Regarding my pending L1 A extn and i485

If you applied for your I-485 when your L-1 was still valid, you could either continue or withdraw your L-1 extension application with no effect on the I 45 application.  You appear to have worked with authorization at all times, so illegality after filing the I-485 does not appear to be a concern.  If the I-485 was applied for after your approved L-1 expired, then there are questions of whether your last entry prior to applying for the I-485 was pursuant to advance parole or the L-1. If under the L1, you are still eligible for adjustment of status even if you have illegal stay of up to 180 days. Under those circumstances, withdrawing or continuing with your L-1A would not appear to make any difference. In the event that your approved status expired by more than 180 days before I-485 filing if coming in on a valid visa, or your status expired by any days before I-485 filing if you were paroled, it would probably be best to terminate the L-1A as immigration officers should be aware that applicants can be excused where a nonimmigrant stay request has not been adjudicated by the time of interview. Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
