I ordered an ITIN through TheITIN.com and had a very disappointing experience. They asked for the required documents, I provided everything, but they submitted my application to the IRS without properly checking the documents. One month later, IRS responded that the top part of my form was unreadable — something the company should have noticed before sending it. They actually informed me about this issue in the chat, but when I didn’t reply immediately, they waited one full month to send a follow-up warning email. This delay alone cost me valuable time. Later, IRS requested company documents as well — which TheITIN.com should have known from the start. Their lack of experience and attention caused even more delays. Because of these three major mistakes, I lost a lot of time and still don’t have my ITIN. I don't recommend TheITIN.com at all. It has been a complete waste of time with zero results.
