Engineering Mechanical Engineering or Computer Engineering?

[nimeet]

im a senior high school student from India have about 3 days in hand having difficulty in deciding between the two careers. I am planning to peruse undergraduate in USA but in a big confusion
Can someone put a clear image about these two branches of engineering as i am unclear about their job aspects at the time of my graduation, growth, and whether i will be employed in USA or i will have to get back to my home country.
Thankyou,
Nimeet

I myself am working towards that job (not sure about computer engineering though). It is a lot of fun and thinking is one of my favorite things to do, as for anything about degrees and what not... I honestly have not thought of that (I am only starting high school ). And for working for the U.S.A. it seems you can for both jobs but it will probably be harder (not sure why though).
