As long as they have multiple entry VISA, u don't need any other docs to send.

hi!

Hi!
Don't think the inivitation letter is also necessary, just good to have. Else they don't need any particular documents.

Ive never heard of an invitation letter being obligatory. The terms for the use of the visa do not change during its lifetime, unless expressly determined by the BCIS...
