if you have whole year of OPT, you dont have to tell that you need sponsorship now. When they get to know you and yur work, you will be so much valuable to them that they will do everything to keep you there. Forget about H1, they will even do residency and everything. Go and work with them and talk to them around may or june, those visas should still be there by then. Without knowing you and yor work why would they sponsor because they can save some money by hiring others here. once they know you, i am sure you can give them an impression, honesty hard work, work ethics, and dedication. If indian can get job, any nepali even from gulmi can do good job because of the workethics. if you talk about what you know, yo dont have to know nothing. They will train you everything at work if its a good company. all you need a gut to take in at training and dedication, if you cant, i dont have anthing to say.
