My situation is the following:
I sublet my apartment to a previously homeless person (I did not know this while subletting). We filled out the sublet form, but never submitted it. He has been living in my room for two months.
He has not paid the rent for this month, and has completely stopped all communication. I am currently traveling abroad, and am unable to talk to him in person.
When I talked to my landlord, my landlord said that I am their tenant, they can change the lock codes for me, and then ask the guy to talk to me.
My questions are the following:
a) Is this illegal? Changing the lock codes, and then asking him to vacate the house? He has clearly violated all terms of the contract by being a month late on rent.
b) The sublet form was never submitted. Does this protect me, if the guy decides to take me to court?
c) I am an international student in the US, and will be starting a job soon. If I am taken to court, and lose, will this affect my record and immigration status?
