My father and I know people who traveled to The United States of America for work. Some of them succeeded and some of them did not. Success, of course, depends upon skill and capability. For example, one of them is a very smart Computer Programmer, and now he owns a medium-sized company there. He's doing very well. 

American dream?

I have some friends (well, they are my father's friends) that have who went traveled to the  USA and they remainded/stayed on there to work... Some of them were successful and some of them weren't. don't. Of course, that depends of on the skills and habilities of each person, for example, one of them was is a computer programmer and he's was very smart/clever. Now he owns a medium sized company there and he's doing great.
