US Immigration from Egypt

I want to ask about filling th DS160

Regarding other names.

I have three old passports the first was having some different I. Alphabets or single letter for example : Moustafa and old passports mentioned Moutafa or Kassem and old passport mentioned Kassim.

My question is that small change is considered other names even the original passport language mentioned the same names in all passport but the changes only in some letters in the English names ?

I'm a J-1 visa holder and it will be finished on june-2023

A restaurant owner offer me to be my sponsor but I'll do all the process and he will provide all documents and signatures needed.

Is that can be done and how I can start??

Hi my beneficiary doesn t have a passport and never had one. I know it asks for a passport number on the application. I was told you can use a birth certificate instead. Is this true?

Is there any issue with a petitioner changing employers while form I-130 is pending?

Hello all! Is it a bad idea to file form I-130 while overseas? Will this cause issues later on? I know I must show I have/plan to return and stay in the US, but with the long processing time, I want to stay with my husband as long as I can before I have to leave.

My thoughts are:

1. going back to the US and stay for a month or so, establish myself (perhaps get a lease with family member) renew my driver's license along with a few other things, then come back to Egypt and wait with my husband

2. file I-130 while in Egypt and move back to the US after it is done being process (with the hopes it is approved) unless this is risky?

I'd love to hear others thoughts and/or experiences so I can form a better judgement on how best to proceed.
