My cousin is in India and her H1 got picked on March 2022 and her employer started the processing, as of today, there are no updates on the H1B receipt copy or number. She is following up with the employer about the H1B receipt, but they say, still it is in process with USCIS, and no updates yet... She has only the I-797C approval copy... Her question is, how can she find out the receipt number with I-797C approval copy? Please let me know ... Thank you - Sneha
