Gizem U. was of great help. This process was smooth and low-effort thanks to TheITIN. It takes a while, but that's the nature of applying to an ITIN.

We truly appreciate your trust, Paolo, and we’re glad Gizem could be there for you to apply your ITIN!

I ordered an ITIN with the expedite option which said it was guaranteed 6- 8 weeks, its now nearly 2 weeks past that with no update. I requested the expedite additional fee to be refunded and still zero response. I am very disappointed.
