employment info and paycheck stubs for non-relatives

[velohorizon]

this site advises sending income info and a letter from your employer for relatives you are sponsoring.

what about non-relatives? what if the person i'm sponsoring is just a friend ?

The purpose of those documents is that you can financially sponsor someone and can take care of all their expenses in US.

Therefore, it would be same whether the person is relative or not.
