US Immigration from Vietnam

Hi can someone tell me where the link is to the live chat for USCIS. I did a search and could not find the info. Thanks.

Hello, I submitted my AOS and it shows it was delivered on April 25 at 12:00am. It has almost been 3 weeks and I have not yet received a notice is action. I am starting to worry.

Does anyone have any advice or suggestions on what I should do? Thank you.

I am confused about the I-864. I am filling online withe CEAC/NVC for the next step. I am doing the I-864 form, but I do not earn enough, so My dad offered to help. Does he also file a I-864 or I-864ez. Is he a joint sponser? Because we will be staying at his house initially and I am still registered at his house while I am teaching overseas, should he file an I-864a as household member?(or not because I am part of his household not the other way round)

Also, family size, my wife is due to give birth in a few weeks so do I log it as 3 or 2? By the time we interview it will definitely be 3

I forgot to add, we will be getting and american passports and Child Birth Abroad for our child. She will not require any immigration paperwork.

Any help would be nice, I have not found much for the online application process.

Thanks

So I'm currently filling out the AOS form for a K1 visa and I have a few questions.
1. I'm a recent graduate from college and I did not make any income last year. My parents claimed me and my younger brother as dependents on their taxes return last year. Because I'm now married, would my household size be only 2 ( me and my spouse ), or do I included in my parent's household since my parents claimed me as their dependent? ( size= 5).
2. My parents have agreed to be co-sponsors for the AOS. Since we resided in the same house, can I combined their incomes as qualifying household members where I will file an I-864 and each of them will fill out an I-864A ? or I will fill out an I-864 and my dad will fill out his I-864 and an I864A for my mom since they filed tax jointly?

Thanks.

Hi guys, We're filling out form DS 5540 and not sure what to answer for question 12 on part 5

My family and I never requested or received any public benefit, should I choose Yes or No? Looks like this question is not applicable to me at all, should I skip it?
