Vague, A friend of mine gradauted from here and started working but unfortunately the company didnt want to apply for H1B. He worked till the OPT expired. He, then, admitted to graduation class. He started searching other jobs simultaneously. Later, he got a job. He asked his employer to file H1B first. Company filed the H1B and he started working there. Everything is fine. So I think you dont have to worry. But it depends on how easily you get the job. All the best.
