Does she have a github account with some examples of personal projects she works on? Does she go to networking events or meetups to expand her professional network, or could she maybe contact previous colleagues to ask for tips on upcoming openings?

I'm not in the states, so I don't know what the employment environment is like on the ground, but from what I know in general getting a job depends on who you know and what others know about you. In other words; getting employed via the traditional vanilla job application route is going to be tough. Especially for immigrants.

She needs to go out and meet people, work her personal network, and have some cool and interesting projects to hook people's attention with.
