Recieved Packet 3 - General questions

[crystalwangg 0]

I just filled out my DS 160 and have everything for my checklist other than Police Records, which I will be going to get tomorrow ( I reckon it may take two weeks or so?) but I noticed that my approved k1 petition expires June 26, 2015. I was wondering if I had enough time for me to get my police records, send in the email for packet 3 and wait for packet 4 to schedule my interview. They said it could take up to 6 weeks, and I'm really nervous about whether or not I have enough time to get my medical and appointment scheduled in time before it expires. I just received packet 3 two days ago. I felt it took a little longer for me to receive it in the mail considering it was right after the Easter holiday. I also wanted to know, other than the NVC fee, (which I haven't received the invoice for yet) and USCIS Immigrant fee, is there any other fees I'll have to pay? As for affidavit of support, my fiance barely makes the bar for the requirement so his dad also filled out the I-134. He did feel uncomfortable having to show his bank statements, but he's a self employed construction worker, and on travel.state.gov, they listed that they didn't need to show evidence of income :

• If you are currently self-employed in any of the following ways, you do not need to obtain submit evidence of income:
  • Babysitter, elderly caretaker, construction worker, handyperson, housekeeper, landlord, musician, nanny, seamstress, tailor, artist, or writer.

so will it be okay to only have the form filled out and not show supporting evidence?

I've been really stressed out/nervous recently because I'm not 100% sure about how much time I have before the petition expires, so I'll feel more relieved once I get a better understanding with what I'm dealing with. Thank you!
