Tell your gf to actually work issue solved

"my GF's consent to impersonate her"
Fraud, impersonation, the wrath and fury of the IRS and tack on a spicy dose of conspiracy.
This is absolutely stupid.
You need to replace that lightbulb in your head.
It ain't working right
I’ve seen crazy but this is next level crazy. To think that people like you are allowed to integrate into society and work like normal people is very scary.
I think the main thing is that impersonating someone and using their information to get a job is called FRAUD and Identity theft and is illegal. It doesn't matter if your GF says it is ok. The other thing is, unless you have authorization to work for a US company and the required visas, this is also illegal. These are 2 potential state for federal charges that you can get if you are found out. That could lead to consequences as a fine, jail, barred from entering the US. You need to reconsider this approach.
Why is your gf not working?
