family visitor--How to obtain a letter from Home Office

[bennyleeshuang]

I'm about to invite my parents to the UK as family visitors. Among the documents I need to provide is 'a Home Office letter confirming permission to stay in the UK'.
If I have a visa and provide a copy of it, do I still need to obtain that letter? Is it just one of the options I have to prove my immigration status in the UK or is it a compulsory document that has to go along with others. If I do need it how do I apply for such a letter?

Thank you very much for your help!

No thats fine if you have copy of your visa attested than thats enough. you dont need any letter from home office.

Hope that answer your question
