US Immigration from England

So we got married in December last year and we are looking at filing taxes. We have read the different ways to file taxes but are confused about how it all works. I assume the best option is for us to file separately but i will explain the situation below to get better answers.

We filed for our i130 this month. The UK citizen has never earned or worked in the USA but i understand we now need a ITIN for the UK Citizen. In terms of actually filing his taxes, how does this work? Do we have to put all of his UK income in a separate tax form when filing separately? I read something about a UK citizen needing to earn a certain high amount before paying tax in the US, how true is this? Will the UK citizen be taxed in the UK and in the US for income only earned in the UK?

Sorry this is like a foreign language to us and we want to get started early

My visa has expired before my EAD has been processed.

And my AOS could be up to 16 more months.

So, although I am here legally until AOS decision - my passport only shows expired visa and I "appear" to be an overstayer.

How do I prove status to a landlord, cop, bank, DMV etc ?

My situation.......

Entered US on business visa.

Met a lady, fell in love and married.

Filed I-485 to change status.

I know it will take up to 2 years ( based on USCIS website estimate ) to get a decision and that does not bother me.

But, in the meantime my only ID is a UK passport with NOW EXPIRED visa. Although I am legally in the US whilst my application is pending, I have nothing to prove this.

DMV refused to renew my drivers license as I am unable to prove my status.

And I-485 receipt letter states "this letter does not grant status".

I called USCIS and they said there is NO document nor letter they can give me to produce to anybody enquiring whether I am lawfully in USA despite my expired visa.

Did any of you guys ever need to prove to DMV ( or anybody else ) you were lawfully here pending your I-485 application ?

Hi all. Just wanted to ask a few questions on the processing times to try and determine how long things will take.

So i have noticed applications from September 2020 (according to other VJ members' timelines) have been approved from Nebraska and some haven't. According to the USCIS processing times it is estimating 6-8 months for the processing of USC Spousal Applications. To follow this and this is where my questions come from, I have also noticed people with timelines from 2019 who have waited 300+ days for i130 approval and a further 200+ days for complete visa approval.

What determines the incredible difference in processing times?

Also, when the case gets sent to NVC and you submit your documents etc. Is there a way of knowing when it will get sent to the local embassy (London in our case and the cases i have been looking at).
