<p>I want to emphasize that it is not practical to assume that you will get a work visa and eventually lead to permanent US residency. My son-in-law is from Canada, graduated from a US law school and now works for a tippy top law firm in NYC. He is still on a work visa that he has to renew every 2 years and it does not lead to US residency after almost 6 years with the same firm. If he gets laid off, he has to leave the US. My daughter is now sponsoring him for a green card.</p>
