This article strikes home for me. I came to the US to go to college, while here I got great grades, a job and eventually married a US Citizen and obtained citizenship myself. Due to the fact that I followed the rules My sister (Medical Doctor in our country of origin) would get harassed and accused of wanting to stay ("like your brother" they would say) every time she came to visit me (For the record she has never overstayed her visas). Eventually when it was time to renew her tourist visa she was denied and told to never set a foot at the US embassy again.

Quite sad really but there is no winning against USCIS.
