Hi, My wife is holding a H4 visa and is currently doing her MS. We want to apply for a COS to F1 for her to be able to do OPT. But we came to know that the current processing times for COS are 5-6 months. We do not want to wait that long for COS. Is there a premium processing available for H4 to F1 change of status? If there is one available, how to apply for that? I found out that I-539 is to be used to do a COS from H4 to F1. Please let me know ASAP if you know the asnwers. Thanking you in advance, Sri.
