Most of the members on VisaJourney have opted to do the paperwork themselves. There are forums available which discuss the pluses and minuses of hiring an attorney. As you can tell from the EasyVisaWeb video, you will still be doing all the work of collecting the information and making sure it is accurate. I don't know what kind of support they provide but personally I was concerned to see that in their video they were filling out some information incorrectly and listing an address as 'stupid drive' doesn't engender confidence. I am also not sure what an embassy attorney is or which embassy the attorney is with. I do hope your experience is a good one. There are plenty of friendly and helpful members on the VJ forums who collectively have a lot of experience. Please browse the forums and ask questions. You will find that you are not alone in this process. Best wishes to you.
Lena&Steve got a reaction from NicholasNissel in What are the chances of failing a k1 visa when we hired a US embassy attorney?
