I already applied for H1 to F1 COS which is currently pending as I wanted to study full time. However, now due to personal reasons, i have to delay the study and want to apply for H4 instead. So my queries are- 1) Is it possible to file for another COS application while the first one is still pending? 2) As I already left my job and started college on USCIS receipt for H1 to F1 COS, will it eb a problem to file for another COS. Thanks.
