Ok my friend needs to get into america..
 

My friend has their VISA already, however they need an invitation letter, does anyone know the *CORRECT* format for a FORMAL invitation letter to the U.S., i've tried google, but nothing has anything official for an invitation letter, any help in the right direction would be appreciated.

Dear {enter name here},

Come to America. Love to have you.

Sincerly,

I've had to do invitational letters for Canada before. Nothing formal was required. Simply had to say the person was an invited guest, they'd be staying with me (and my address) and for how long.

Your best bet is just to call US Immigration and ask them what they require. It's free and they should know. :thumbsup

What he said. As long as it's signed and preferably notarized, it's straight.

I never had that problem, so I dunno.

just hide him in your basemenet
