Olori D.
The customer service was polite and on point. All my questions were answered and my expectations were well managed & I was to expect my ITIN in 8-14 weeks but I was pleasantly surprised that I got my ITIN number in 7 weeks. Fantastic experience all round and I have recommended to other friends. Thank you Gisem. U for your help. You were great.

Agradezco al equipo de TheITIN, especialmente a Gizem U, por el apoyo y acompañamiento brindado, siempre estuvieron pendientes de atender cualquier inquietud; pensé que no iba a obtener mi ITIN, por estar fuera de USA, pero gracias a Dios y a ustedes logre obtenerlo. Muchas gracias.
