My PERM is in progress and I am currently on H1. I need to convert to H4 and take some time off for preparing for an exam. I look forward to convert to F1 for higher studies after that.
a. Does this change in statuses invalidate my PERM application if the employer still keeps it valid?
b. I am hoping I can manage without taking a break from work. What is the average time taken to convert from H1 to F1?
c. My H1 is expiring on Jan 20th 2013, can I apply for COS to F1 on Jan 19th? Will this adversely impact my PERM?
