Hi!  I am the Community Outreach Director at SimpleCitizen, so I am obviously biased toward SimpleCitizen. That being said, I will make this answer as objective as possible.SimpleCitizen and CitizenPath are both reliable solutions according to customer reviews. However, SimpleCitizen offers more features including unlimited attorney consultations, RFE preparation, document translation, etc.Fileright, not so much. In fact, their parent company, Forms Direct, was just fined $2.2 million by the FTC.First, Price:SimpleCitizen is a one-time fee of 348 dollars for the entire Green Card Application. This includes support until the day you get your Green Card (i.e. RFE prep, attorney consultations, etc.)CitizenPath charges for individual forms. The I-485 is 197 dollars, Form I-131 is 87 dollars, Form I-130 is 97 dollars, Form I-765 is 53 dollars. That would total 434 dollars.Fileright also charges for individual forms. They charge 199 for Form I-485 and another 199 for Form I-130. If you’d like to also get the I-765 and I-131 with your application, they charge an additional 199 for those. That would total 800 dollars.Second, Features:At SimpleCitizen, we have 20+ applications. We include an attorney review, live chat for customer support, USCIS certified translations, printing and assembly of your application, unlimited attorney consultations, complementary RFE response preparation, case status tracking/automatic email and text updates, and interview preparations.According to their website, CitizenPath has an attorney review, printing and mailing, and live customer support.Fileright has 24/7 support and an automated software review for errors.Fourth, Refund Policy:SimpleCitizen has an unlimited 100 percent money-back guarantee. If the application is rejected, we cover your fees. If you are unsatisfied at any moment, we will refund 100 percent of your SimpleCitizen fee.CitizenPath also has a money-back guarantee. They guarantee that USCIS will approve the application. If it is denied, they refund your prep fee and filing fees.Fileright has a strict refund policy. Their refund policy states you can ask for a refund within 30 days of the original payment or before an application is completed or downloaded.Fifth, reviews:At SimpleCitizen, we use reviews/customer feedback to understand how we are doing in the process and how we can improve. On Facebook we have 58 reviews with a 4.6 rating. On Google we have 122 reviews with a 4.9 rating. On Trustpilot we have 4 reviews that all have given us an excellent rating.CitizenPath: doesn’t seem to do reviews on Facebook or Google. Their Trustpilot has 279 reviews with 81 percent excellent, 10 percent great, 2, percent average, 1 percent poor, and 5 percent bad.Fileright has 82 Facebook reviews with an average of 4.1/5.
