US Immigration from Jordan

So i need to fill the 160 ds form for my k1 visa to schedule an interview then i have to go to this website to log in and make an appointment from there
what i want to ask is , does anyone has a video that teaches you the steps 1 by one and what do i need to have first before filling the 160 ds form
do i have to wait the embassy to contact me first ? or can i do it right now since my visa says ready on the https://ceac.state.gov/CEACStatTracker/Status.aspx?App=IV
thank you very much in advance.

So i just check my The Nvc site and it said that my application is ready , What next , what do i have to do?
do I have to schedule the interview or they do it ?

I received an email yesterday from the NvC that our petition is being sent to the Embassy. In the email they spelled my fianc s first name wrong. Do I need to have this corrected? Or is it not a big deal since it s just an email

In the next two months I'll be able to apply for citizenship. I came to usa at k1 visa about four years ago and I got my first green card about two and half year ago. So I will be eligible in not two long. And I've been using attorney for my green card.

But I saw online that you can file for citizenship online and it doesn't sound hard.

Do you recommend file online by myself and save some cash? Or you think it's better to use an attorney since its the last step?

Tell me about your experience if you used the online by yourself

Thank you all

So my husband received a GREAT job offer. He already has a social security number. He just did his biometrics yesterday after waiting only 7 weeks. Before my question, here is my timeline:

1/7/21 - Mailed AOLS pkg. Adjusted from K1. Sent I-485 & 765

1/27/21 - NOA1 for I-485 and Rejection of I-765 for filing on older edition.

2/8/21 - Mailed new I-765

2/20/21 - BIOMETRICS SCHEDULED (less than 20 days from NOA1)

3/10/21 - EAD updated into USCIS system and receipt text to me

3/18/21 - Completed biometrics

3/19/21 - USCIS emailed action on case which basically states USCIS is reviewing his case

My husband received a great job offer and they want to hire him as soon as his AOS is completed. He wants to lessen burden on me and help but also wants to be a taxpayer and start paying into his own social security. IS IT TOO SOON TO REQUEST AN EXPEDITE? I have heard in this very forum in the past that its risky to request it. How can it harm us? Thanks for feedback.
