International Student working with an uncooperative landlord and want to terminate the lease in the US. Help.?

My friend is an international student, and she is renting an studio. The studio has an uncooperative rental office. She terminated her study in the United States due to emergency situation. And she want to terminate the lease. Her friends and she has been calling the rental office, going to the office and also wrote a formal letter to describe the situation. However, there is no responses from the office. I assume the office is being rude here. As the result, I have come up with several plans as follows:
1. Sublet the studio
This is a poor option because it has been a month but no one is interested in it. We have tried craiglist, facebook, and the school too. We have been lowering the price. Subletting is bad idea in this college town.
2. Let the landlord take the deposit and stop paying rent for a studio that she don't use. The problem is she may want to be back to the US.
3.Continue to pay the rent. It is an impossible option but I list it here anyway. She cannot afford to pay though

Comment on Plan 2.
She may come back to the United States again for studying. With this uncooperative landlord, it ruins her life.

The goal here is to resolve this situation while she can still go back to the US for studying. Or if this plan is executed, will the US immigration find out she is not paying rent?

Comment on Plan 3.
She was an international student, and now she is back to her home country. Her home country is a developing country with high unemployment rate. Therefore, she cannot afford the third plan.


The goal here is to resolve this situation while she can still go back to the US for studying.

Question: What should she do? What are other options?

I do not want answers like this:
"Can we go to your country, rent your parents' summer-house and not pay the rent and then scarper back to the US? Would that be OK by you?"

Please only provide concrete answer to help my friend's situation.

Look at the lease agreement. Many times you can terminate a lease and pay only an extra month's rent. That's not a bad deal. (This is in California.)

Also, go to a public library and ask the reference librarian to help you find books on "the rights of tenants." You could also explain your situation to the reference librarian and he or she could recommend books that would be helpful. (This is a very common question.)

Good luck.

Hey good to see you here again. where you been?
