US Immigration from Jamaica

Hey VJ fam,

My hubby petitioned for me when he was a LPR back in 2018.. It got approved in January 2020, I have a son before marriage and he now wants to petition for him (he's also here in the states with us). Last evening he gave me the go ahead to do the petition online (ofc with him right by my side) but after filling out majority of the document, we became stuck at the uploading of documents part of it. Not all applies to us, but I'm still a bit confused. These are our options of documents for evidence of relationships:-

1.Proof of us citizenship- we uploaded certificate

2. Childs BC- this was uploaded asw

3. Proof of marriage to childs mother- uploaded marriage cert

4. Proof of legal termination of prior marriages- N/a to us

5. Proof of parent-child relationship- Clueless

6. Proof of stepparent/stepchild relationship- not sure if I was supposed to upload the marriage cert and sons bc again but I did.

7. Proof of legal name change: n/a

Then it asks for secondary evidence if a reqd document is UNAVAILABLE

Such as religious record, school record, census records or affidavits.

We are a bit clueless as to some parts of this: I've highlighted the confusing issues above.

Does anyone know at which stage dna is requested for adult children?

After sending all requested documents, I keep checking on the status of the case and up on checking this is what I saw. Should I be worried or just wait

If someone enters the U.S on a tourist visa and decided to overstayed their visa and remain in the U.S 5 or 6 years. Can they file to adjust their status to permanent resident? Would they be able to petition for themselves or they would a family member to file the petition on their behalf?

I did a payment for my fianc to do the interview in Kingston, Jamaica for the k1 visa and I was charge $281.11 instead of $265.00 Has this happened to anyone else? Or is this just taxes they added onto the fee?
