Can and should i apply for aos with an approved i 526 awaiting a consular interview while being in usa on a b1/b2 visa ?

A concern with USCIS may well be why you are applying for adjustment of status here while you are awaiting a consular interview on the approved I-526 petition, and the related concern of whether you had a preconceived intent to adjust status when you came to the US. It may come down to an immigration examiner’s perception of what is going on. There is probability that you will be interviewed instead of an interview being waived, and in such case, the examiner may question and evaluate your explanation. I do note that the deterioration of conditions in India vis-à-vis Covid would appear to be a reasonable explanation for deciding to adjust status instead of returning for consular processing. If you are refused, you may face problems with your consular processing in India dependent upon the speed of resetting consular processing and the attitude of the interviewing officer toward your attempt to adjust status in the States.  Due to the limitations of the Lawyers.com Forums, Alan Lee & Arthur Lee, Esqs.’ (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.
