I had an amazing and smooth experience!! I would recommend everyone doing their ITIN with Sina
The process with the company was very straightforward. It involved a quick interview and a few forms, and that was it. I received my ITIN in about 4 months, though this included the holiday period, so some delay was expected. Overall, if you’re looking for a simple, no-hassle ITIN process, Filing Express is a solid choice.
I used Filing Express for their ITIN service, and I am extremely satisfied with the level of professionalism and support I received. From the beginning, Sina Bonabi clearly explained the entire ITIN application process, outlined the necessary documentation, and guided me through each step with patience and clarity. Communication was prompt and consistent; all my questions were answered in detail, and I was kept informed about the status of my application throughout the process. What I expected to be a complicated and stressful experience turned out to be smooth and well-organized, thanks to their expertise and attention to detail. I recommend Filing Express, Sina Bonabi, and their ITIN service to anyone seeking a reliable, knowledgeable, and efficient team to assist with obtaining an ITIN.

I had an excellent experience with Filing Express and their ITIN Service, especially with the help of Sina Bonabi. Despite the obstacles and delays caused by the recent U.S. tax season and the U.S. government shutdown that significantly affected IRS processing times, they still managed to successfully obtain my ITIN. Sina Bonabi and the Filing Express team were very professional, responsive, and clear in their communication, providing detailed instructions and regular updates throughout the process. Even though everything was handled completely online and I am based in the Philippines while they are in the U.S., the process was smooth and well guided from start to finish. Although the waiting time was longer due to circumstances beyond their control, they remained patient, supportive, and committed until my ITIN was successfully issued. I truly appreciate their dedication and highly recommend Filing Express and Sina Bonabi to anyone who needs reliable ITIN service.
