As long as you have your medical documents to show diagnosis of your condition, it couldn’t be easier! It costs 200 to do the interview but the Entire process took less than an hour. Fill out the forms, upload your documents, then they immediately call and video chat through your evaluation. After they reviewed it and spoke to me, they uploaded my certificate in half hour. Dr Truong was very knowledgeable and kind. Whole scary process made comfortably and easily! So awesome
