US Immigration from Nepal

Below are the steps I, the Petitioner, took to complete form I-129F and successfully received the K-1 Visa for my beneficiary:

I submitted my I-130 and I-130A by filling it online and attaching the PDF in evidence section. Before I submitted it, I opened the file and everything looked fine. However, today on a new computer with Adobe Acrobat DC (full version of adobe reader) I looked through my submitted I130A and it is showing blank because of some security encryption stuff I guess the form comes with. It still opens normally on a website pdf reader/adobe reader on old computer and shows that I filled in everything appropriately. If USCIS uses Adobe Acrobat to open PDF, I am probably screwed... Should I be worried?

Should I just print out the I-130A and add it to the unsolicited evidence just in case?

My MIL's B2 extension request approval:

Initial I94 expiry- Jun 2021

i539 filing- May 2021

Extension Request - till Sep 2021

Biometrics - Aug 2021

US Departure- Sep 2021

i539 approval- Jan 2022. The new i94 has validity from previous i94 expiry to Departure date.

It is good to know uscis approves such extension requests even though they are processing it months after the maximum allowable request of 6 months.

For example Nebraska and certain other centers have 7-15 months of processing time, while California has over 2.5-3.5 years!? Just found out my I-130 for spouse as USC, just got send to California...this doesn't make any sense. Wouldn't they want to distribute eventually to all service centers? Could someone explain

I filed online and received a receipt of notice today. I tried to google it but couldn't come up with an accurate answer. At the bottom, it does mention Nebraska Service Center on the receipt, will this be it? Thank you
