Hi, I use to share my house, with a person who was on a student visa, but his visa expired and he never told us, and moved away. Now, his deportation letters are coming at the house I live? How do I stop them or inform home office about this? They have began the removal process so what should I do now? My place is rented, I don't own it.

Start by retuning them to the sender... and state addressee no longer lives here.

Also write the forwarding address on the envelope, if you know it.

How do you know what the letters say? They are addressed to your former house-mate, not you.

And why are you opening, is official government letters to know what they say?

You should not be opening the official mail of another person.

You merely send them back,
