What countries are you from originally? Plan a holiday to the US, look things over and then make a budget (emigration is far from cheap), save and then decide to back out or bite the bullet. Don't do anything permanent until your visa is in the bag for you, your spouse and your child. Hollywood and anecdotes are not good inputs to a life determining decision like this, consider it a huge project and devote resources…
It also seems that education is payed a lot more attention to than some other countries. Don't get me wrong, I understand the value of having a good education, but in the tech-world I cannot believe a certificate/diploma is worth more than visible passion and experience.
