Using Bitcoin To Create An "Educational Trust" - Possible?

Happy Friday! I am trying to understand more about how crypto currencies, exchanges, wallets work. Specifically, I’m trying to figure out if it’s possible to use crypto to essentially create an “educational trust” of sorts.

My girlfriend wants to come to the US to study for a second Bachelor degree, but doesn’t have the required savings. I’m willing to pay for the education for obvious reasons, but the US Government requires her to have a full year’s worth of tuition to qualify for a student visa. The money must be in an account in her name.

While it isn’t that I don’t trust her, there’s trust and then there’s stupid trust. There is a world of difference between my giving $10k to a university for her tuition and me giving her $40k with no strings attached. Just so much difference.

However, it seems that USCIS will accept Bitcoin assets as proof of financial capability. And it has been suggested to me by a friend that I might be able to use a crypto exchange or wallet to create an account in her name that I effectively control by holding the keys. Or at least holding one of the keys. I guess there are dual key systems?

In order to work, it would need to have the following qualities:

1. Have some kind of display or ideally a “statement” (like a bank statement) showing how much is in the account.

2. Probably the current value of the Bitcoin.

3. Show her name as the owner of the account.

4. Have a key that I hold that would prevent her from just transferring to another account.

5. Allow accounts to be created by Russians.

If there’s a way to accomplish this awesome, I would appreciate any help.
