Generally, yes. Plus other forms such as I-131, I-765.

Are you even sure your sister is eligible to adjust?

Yes, as there's nothing else to provide. Sometimes you'd get rent increased and a letter addressed to tenants. I'd attach that potentially too.

Requesting combo interview by sending a letter. Yes, where you are going to have N-400 interview. Write to that field office.

Did she move addresses after interview? I wonder if decision was made but sent to old address?

No reason to hold off. File in April.

Which is clearly wrong? If you're married you have to file MFJ or MFS

You'd likely get RFE for not including all pages. Send complete statements. Don't worrry about saving the planet, don't worry about saving few bucks, only worry about saving time with USCIS.

Seems logical to me. In USCIS eyes, an RFE was sent, you never responded, case got denied. Now, it looks like you have proof of filing for change of address? If you decide to fight the decision by filing I-290b, you should walk USCIS through the timeline and explain how they denied you despite you notified them of address change.

1. At the time of applying for N-400 under 3 year rule would you have at least 18 months of residing in the US in the last 3 years as LPR? 2. That's where the issue may be. Some immigration officers will interpret marital union rule very strictly. With you and your husband being apart for some time, they may claim this rule was broken, making you ineligible for N-400 under 3 year rule 3. Again, this is where the issue may be. Having just a phone is not strong evidence of keeping ties to the US. Lease, bills, banks may needed. Do you have driver's license with your current adrress? Also, for N-400 under 3 year rule you may need to open a joint bank account and start using it sooner rather than later. You need to show you share finances with your spouse, even if you don't contribute to it right now due to no income. Do you file taxes jointly? TL;DR If you want to have a go, you can. You may lose filing fee and would have to reapply under 5 year rule. This is not a legal advice

- Will you have enough physical presence in the US when applying for naturalization? - Will your US citizen spouse be with you all this time? Remember marital union part when filing under 3 year rule - Will you keep properties, accounts, other ties to the US while away?

Yes, in most cases it's a better route nowadays

Why don't you add the spouse to utility bills?

The way I understand it, US sees your first marriage as legal. US doesn't allow being married to several people, thus second marriage is not valid.

They don't have to give any reason

Yes, updates are not always accurate or up to date. The same goes for processing times and estimates. And "Ask Emma" or talking to an agent sometimes results in more confusion than help - those agents make things up half of the time. E.g. people get told their interview is waived, where in fact it wasn't etc etc. I knew my GC tracking number from USPS Informed Delivery few days before it got updated on case status page. I'd only believe in NOAs / RFEs and what they tell you. Everything else is unreliable.

They actually call it emergency passport? https://en.wikipedia.org/wiki/British_emergency_passport It makes sense, at least most European countries make it one way / single use due to security.

Can you submit an inquiry? Are you sure the card wasn't mailed / lost? Sometimes the status doesn't reflect the reality.

Yes, you may be asked for those.

No

I am in the process of filing, just waiting for few more docs. Yes, will be getting some refund.

Sure. I think thi evidence may not be as important, compared to joint taxes, utility bills with both names, joint bank account statements. But you can take it just in case, it won't hurt. If it shows history of purchases, why not.

If somehow it has both names or money is drawn from your joint account etc?
