if you don't have a job it is not a good idea to file for H1 right now, especially with dhoti consultancies. After the arrest of those 11 people a few weeks ago, it would be wise to be extra careful. Some of those 11 arrested were employees, and they are arrested for "submitting false documents". The H1 B visa process will be lot more stricter this year..so if you don't have a job its better to extend OPT. Also if you plan to join college later on, then it will be hard to change from h1 to F1.
