I was recommended by a friend who was weak in Eb1 but also got approval easily. I hated to write recommendation letters myself so I decided to hire her after thorough discussion with my friend.
I also don't like the consultation fee but since I decided to hire her it was included in my legal fee.I did not pay extra.
She gave me 3-4 examples and asked me to write input statement of all my achievements, usually 30 pages. Then she drafted 5 letters. I was very satisfied with her letter since she knew biology she wrote it pretty well and after reading the letters I really felt I am an extraordinary figure with tons of strong evidence to support. That's the intelligent and impressive part.
They are expensive! I felt regretful after I ted 140. And worried if I could get approval since my case is not strong.However, now I feel it's worthy. If I can get EAD 1 yr earlier, this extra $1000-2000 is nothing.
