US Immigration from Tunisia

Hi all,

I need your input regarding I-130 online filing for Siblings/Parents of US citizen. I have hard time understanding the questions "Prior Petitions" and "Other Petitions" under the section "Other information"

1. I already filed for Parent 1, so
   1. under "Prior Petitions" I answered no prior petitions
   2. under "other petitions" I added all sibling I am planning to file I-130 for + Parent 2
2. For Parent 2: I did not file it yet, but here what how I filled it so far:
   1. under "Prior Petitions" I answered yes I have prior petitions and I put the petition informations for Parent 1
   2. under "other petitions" I added all sibling I am planning to file I-130 for.
3. For sibling N1 I am a little confused how to fill it:
   1. under "Prior Petitions" I answered yes I have prior petitions and I put the petition information for Parent 1. But I can't add a second petition to put Parent 2 's petition information ==> Any idea how this should be filled? I guess my understanding for this field might be wrong, if so can you please help clarify it?
   2. under "other petitions" I added all sibling I am planning to file I-130 for except sibling N1

Here a capture as an example :

My fianc (the petitioner) quit her job last year do to covid and is now working part time , which is something like 13k/15k a year with tips . is it a bad idea to go for a k1 even tho her parents are willing to co-sponsor and they make well above the minimum requirement? (they are willing to provide accommodations at their place too) would that cause a K1 denial ? its the Tunisia embassy btw .

Instead of typing my name on the letter of intent to marry , i wrote it with a pen , is that a no no?? Should I redo wich means weeks for it to get to the US XD

Hello , so we are doing the complementary files FOR THE I-129F, is it okay if we number the pages and put a title in the BUTTOM of each page ( example : proof of in person meeting 1/15) ( WhatsApp texts 1/20) . Didn't see anyone does that in any guide , is it because its not allowed?

Me (27M) and my fianc (22F) met on reddit April 2020 and were on a long distance relationship talking / video calling daily . due to covid delays, she was able to visit last month for 2 weeks which we spent entirely together and in which we got engaged in the presence of her mother and my family . my question is , is it risky to file the i-129f after only meeting once even if we can prove that we talked daily for more than a year online and that it is a serious relationship since both our families are involved... we are not meeting again until between October/Christmas again cuz covid hit hard financially ... any help would be much appreciated
