I think you are very fortunate because you have family over there and you speak English. The family ensures that from day one you will have a roof over your head and three warm meals without spending a penny. Since you speak English you can instantly pick up a basic job. When I first came to the US more than a decade ago, I had to pay for everything myself from the moment I stepped on U.S. soil. Coming from Indonesia where English is not an official language, I didn't speak the language fluently, which made life more difficult.
Without boring you with the details, let me just say that I worked my *** off during my first six years here. They were really the hardest years of my life; so hard that I almost burned out toward the end when I finally landed a decent job.
Yeah - I moved to Canada with a friend when I was 18, didn't know anyone in Canada nor did we have a plan besides our first week booked at a hostel, but it all kind of just fell in to place and went great for me. Only came back for family reasons, so I've decided Canada is still a high option on my list next year if I can't get to the US another way. But I can imagine it would be incredibly hard not speaking English as well as not knowing anyone.
