Do not use this service! I hired them Aug of 2022. It is Jan of 2024 and I never received my visa. On top of that they submitted the wrong visa. I had to withdraw and start over. One of the agents I spoke with was nice and helpful which is why I'm giving 2 stars instead of 1. The member Alex is the money collection person and does not take the time to explain anything. He uses fear to make you feel like you need to pay. He lied to me about accepting the ITA - that it will hurt me getting a visa if I do not accept that day (I asked two different lawyers about no accepting ITA and they told me what he told me was wrong). The company does not tell you upfront how much anything is. I knew it would be expensive but they blindside you with the cost. I have been emailing them since I had to withdraw my application but no one will respond. Find an immigration lawyer - it's cheaper. Do not use this company! Update #1: I emailed UIS on 2 Jan and they said they would get back to me in 48-72hrs. I emailed on 9 Jan as I hadn't heard back from them. I emailed again on 20 Jan as I still hadn't heard anything. I made a review elsewhere and less than 24 hours they responded. Less than 24 hours after that they called. It's been 2 weeks and I got one follow-up after I emailed them again. They are still looking into my case. Will update again when I hear back.
