Request for new I-129f

[G+A 5]

I just got a letter requesting to send a new I-129f. The orginal that was sent was completely incorrect. I realized this upon recieving NOA1 Jan. 7th. I wrote a letter of explanation..and included the correct I-129F and mailed it the next day. After also calling USCIS, soon after finally was able to get ahold of a tier 2. Explained the situation and he took down the correct information for both my fiance and I. My question is should i just immediatly send another I-129f even though i already mailed one before their request for it?...Which i have no idea if they accepted or not. Also what should i include with my new petition if anything. Maybe a copy of the letter they sent me? In the letter they say "please fill out a new petition, date and sign it and return it to us."

Another question maybe stupid..but is it ok to fold the I-129f and put in a normal envelope? Personaly this bothers me since it's an important document..the corrected one i sent i used an big envelope so as not to fold.

I really want to get this right, no more mistakes.

Thank you very much

If you sent one in before they asked it will most likely get lost. You should do as they requested and send it in again. And you could just try buying a bigger envelope.

I would send another one also, in a big envelope.
