Cr1 I-130

After I filled and uploaded documents on my USCIS account, I only able to see a very few categories for file uploads.

Since last week I started seeing many other categories like I-864, G-28, Police arrest report and such as others.

It's a standalone I-130 petition for spouse living abroad.

Does anyone know why categories was added?

I haven't received any notices after the receipt notice.

Does it mean the file is picked up for review and hence USCIS open up the other categories dynamically?
