I started the I129F form on my own and thought I could complete it without help. But I ran into some problems; the fillable form the government publishes has some errors in certain required fields that lock you out. And some areas could have more than one interpretation. So, I went to Citizen Path and was SO happy with the results. I completed the I129F using Citizen Path and compared to what I completed on my own - and I had made several mistakes that would have possibly caused a rejection. The Citizen Path online form is AWESOME and EASY and it?s so simple to edit at the end if you need to. This is an excellent service and I recommend to anyone who is a DIY?er like me; just better to have some expert help.
