US Immigration from Pakistan

Hi,

I have once again returned to my visajourney family for help...

Here is my situation. In 2015, I sponsored my mother. The entire process went smoothly and she received her permanent residency status within 8 months. She stayed with me in the US briefly, but due to a family tragedy back home, had to travel back. Since she had ended up spending more than a year in Pakistan, we assumed that her residency status would be deemed abandoned. Now, after 5 years, I plan on sponsoring her again and am a bit rusty on the process. What do you seasoned members think? Would her previous abandonment have any bearing on a new application. Is there anything else I can do to expedite the process? I was advised the SB-1 application, but we really don't have a reason to show that she was out of the USA for reasons beyond her control. Also, are the I-130's online or still paper format?

Thanks you all for valuable input and advice.

Sent it our I-130 and AoS packet in the mail last Tuesday. It was received on Friday.

My sister-in-law is expecting her first child in December and my spouse would really want to be there, but with the current delays in processing, is it even possible?
