We did this entire process ourselves, we did not use a lawyer. Please feel free to email me through this site if you have any questions, or need help going through Casa, I will do my best to get back to you. Good luck in your journey!
Tany, I'm from the original August 2009 K1 visa filers and saw today that after 2.5 years you are finally approved. I am so happy for you two and I wish you the best of luck
