They will ask you when your OPT starts.. they will file for your H1b regardless if you are undergrad or masters as well. But limited quota.. 15 seats total and you must be a pro developer and experienced!

If you get your H1b, you commit for few months duration. Compensation matches industry standard with a min of 60k and no catch. They place u to fortune 500 companies.. so make sure u know how to program.

They also do require applicant must be Computer Engineering and Computer Science Majors (either from US or foreign country with 4 years bachelors holder/ Note: not 3 yrs degree) with a minimum of 2 years of professional proven experience.

My friend is being sponsored currently with them under undergrad quota.. so.. good luck..
