Thank you all for your responses and suggestions.
The applicant is actually my wife.
@sailahari: We're in Houston. Undergrad major (obviously) was business administration, and MBA is with Finance concentration. Like I mentioned in my OP, she has some experience but that was in Nepal. No relevant job experience in the U.S. If you have any contacts here, please let me know.
@ujl - pretty accurate article. but in our case i think the bias is very explicit because companies don't want to continue talking as soon as they hear that my wife is not a permanent resident/U.S. citizen
