i am worried, my status is neither f1 (as it expired long time back) nor h1(as the case is stil pending), I am stuck with any govt. related work like renewing my license , my all documents are genuine, currently working as well...

i am thinking whether it is wise to withdraw h1 and file for CPT or keep waiting until i hear from USCIS...also i wanted to know if our sevis ever expires, how do i check whether my sevis expired or not...

please advice!
