you should follow June's fillers then to match with other people within your time range

Regarding the processing time at the state you going to, it won't make it any faster. They will transfer your file to another office and assign it to a new office, which will delay your case for only god knows how long, could be 2 weeks and could be up to 6 weeks

Basically no one will ever ask you if you're in the US legally or not. For identifications, state ID/DL is more than enough. Either state or federal agency or even for domestic flights, you can travel using your license.
 
general tip: avoid taking your passport in public to avoid loss or damage. 

Yes, you can do both with your EAD, once you get the card, get your passport, NO1, and EAD and go to the DMV/SS center
Now you/her should just kick back and relax, and wait for the interview notice.

I believe it's better to call them, say you want to expedite your AP because of your wedding *mention date*, then they may ask for evidence so be prepared to send wedding invitation with dates, flight tickets, or whatsoever you have

You can easily expedite your AP for your wedding abroad... EAD? Honestly no one seems to know how they process it, how long it takes, the effect of the RFE/RFIE on it (It doesn't make sense to assume a RFIE after 60 days would reset it to day 0 again), so really just don't stress on it. 

They usually take up to 7 days from arrival day to process the docs.
so don't worry.

SInce I am a May-April Filler, I thought I'd share my timeline with everyone here as I noticed my timeline is very close to lots of folks here;
AOS from F-1 Visa (Been in US for 5 years now)
 
Package mailed: April 30th.
Delivered May 2nd. 
PD for (I-130, I-765, I-131): May 2nd... MSC 
PD for I-485: May 8th.
NOA: May 12th, May 15th in mail.
Biometrics letter: May 18th.
Biometrics done: May 24th.
 
 

I honestly think you should read the instruction very well before sending. You should find the address if you click on where to file in the main page. 
And if you look in the instruction, you will find the example of the evidence. You can send photos, but don't send photo albums. 
 
Once again read the instruction very well, and only send what they want you to send. Additional info could be provided by you in the interview

I'd also recommend to go after noon like after lunch hour for any gov related walk in (SSN, biometrics, DMV,...etc)
afrer lunch is usually the best time to drop in because people go for morning dates 

I just did a walk in for my biometrics today. I was schedule for May 31, hopefully get my EAD and AP within the next 45 days 

I know each embassy is different on what they except. When we filed with assets only, the interview letter said to bring a co-sponsored I-864 to interview.
 
At first, we only showed a few assets that were liquid and well past poverty levels...more than 10X. They didn't like that.....We loaded up our guns and brought deeds and property taxes for 5 investment properties that are paid for. The deed to our US residence and the pay off letter from the mortgage company. Statements from 4 investment accounts, 2 money market accounts, 2 checking accounts and my IRA account for the last year. They excepted that at interview without a new I-864.
 
The problem with a joint checking account is you are not the soul owner.....Also is known that some people move money around for visa's. That is one reason they want to see past statements with history. I am not sure about this, but also they would like to see future stability....A checking account is not that.
 
Some people here at VJ used assets only for AOS......hopefully they will chime in and you can get a better idea on what is needed. In my view (having been through the process) I don't think a joint checking account is going to cut the mustard.
