I really wanted to mail mine out first thing WED but I am glad I waited because since then I have talked to 2 pro bono lawyers who have given me great advice on cover letter, index and obtaining more evidence as I am in a pickle since I dont have a bank acct. I thought early bird gets the worm but for us older dreamers that have to explain gaps I think its better to take a deep breath and make sure you make the best case possible! Best of luck!
