I liked what kiddo wrote in this thread. My experience is finding a job in America is anothe project work or thesis work. It takes at least six months to get a job if you start looking for job from today. You should not be frustrated at all because everybody undergoes in this way. Besides, you always have to polish your resume to match the job posting. Resume should reflect your experties. Spend more time in the beginning of job search to make your resume. Learn job finding techniques and manners. You may find some in websites such as careerbuilder.com. In the job market, they actually look for a person who is well fit in that position. They do not like to see some who recently hired is a failed in that job. If you get phonecall for interview learn how to respond. I am sure you will learn how to respond in an interview only after you are declined from first few interviews. You need to count it as well as a process of finding job.

Networking is really important for job search. Be curious about job oppertunity. Talk about your job search with advisors, professors, seniors, friends. Do not think other people will take that job if you talk to others. Email the people in the company about your interest. Grab the oppertunity to talk with people in manager level in seminar, workshop, jobfair etc. Show your geneous smartness. If you can target what kind of company you like to work in. Excel you expertise or learn such subjects what they are looking for. In America, good is not enough, you have to be excellent to beat American counter part. So, try to build a speciality which can distingush you from others. Finishing the course and graduating from a college is not enough. If you think the field you are in is  hopeless, do not regret to change the field or going to higher degree. Higher degree schooling is not the priority of Americans, it could be your chance.

Be positive, think positive. Otherwise you will ruin your interview. I suggest to do some mediatation (pranayam) regularly for positive thinking and making your brain healthy. The problem in front of you is looking at you if you can solve it. If you can overcome or solve this problem there is a meaning of your degree, otherwise you need to learn more.
