I'm looking for serious recommendation on what to do right now in my life. I'm currently 25 year old with roughly two year of industrial experience and looking for a career change. One thing I absolutely want to work out is by applying for Master's program from a US university and finding work after graduation which will require H1B visa. Is this a wise option? I will be moving from a third world country and be mostly on self finance Masters. I know it will be expensive but I'm seeing it as an investment which will pay off. The intended field is in the tech side although I have a degree in Mechanical Engineering. Did this new bill make it far more difficult to get work visa or will the lottery system work? I have a lot to lose if I don't get a work VISA really which would force me to return to home country. Note: I'm not from India
