US Immigration from Sweden

When the petitioner files also for a step child (beneficiary, CR2), how does filling the forms and attaching attachments differ from the spouse beneficiary process? We are now so confused as the online form is all the time mentioning the spouse beneficiary... and when filing a separate petition for the step child, most of the questions are non applicable (such as work history for a baby). In addition, should the CR2 application have all the same attachments than the CR1 PLUS extras such as the child's birth certificate?

When I apply for my first U.S. passport, do I need to submit any documents for the name change I had when I naturalized? Or do they automatically go with the name that is on the Certificate of Naturalization (that clearly shows my new name)? I only dropped one of my two middle names, so it wasn't a big change or anything.

(And yes, I searched visajourney and didn't find what I as looking for (I really dislike the VJ search function), and the DS-11 form only directs me to the passport website and I can't seem to find the right answer there either (only info regarding name change for people who already have passports).

So I apologize, as I'm sure this has been asked before.)

We are overseas where we got married and my spouse is ready to file online for the CR1. However, she cannot access her USCIS account she created before traveling to Europe because the phone number she used for that account is not working outside of the US (so she is not receiving the verification codes). She tried recovering the account etc but nothing works. USCIS customer service tried helping but could not.

Is it possible to start from the scratch and create a new account and use another phone number for the new account (that works here in Europe)? She has not used the "old" online account earlier for anything else.

We just got married last week in Europe and we are now ready to file for the CR1 visa. We are also planning to visit the US in a couple of weeks. Should we wait and NOT file yet and do the short trip first as the border agents might think we are wanting to move in already etc? (which we are of course not)

Guys...I'm so lost and don't know what to do.
I'm a US citizen and my goal is to get my 2 siblings (and parents) to live with me.

I thought, if I petition for my parents and they come, it will be quicker for them to petition for siblings.
I even thought after my parents come here, all 3 of us could petition for my siblings together so it will go faster. I believed a parent petitioning for a child is quicker than a sibling doing it.
But now I heard that because my sister and brother are both married (& have kids), my parents can't petition for them until my parents become citizen (which means we have to wait 5 years after my parents are approved and received their greencard).

I already have petitioned for my parents, the only thing left for me to send in is proof of my income and taxes and affidavit of support.

So I thought of some options:

OPTION A:
========
Me petitioning for siblings right now while finishing the petition for my parents simultaneously

OPTION B:
=========
My siblings getting a divorce. And when my parents get approved, me and my parents petition for my siblings (not their partners or children).
When my siblings get approved, they can re-marry a month before and petition for their spouse and children.

The first question is, what would allow my siblings to come quickest?
if I go with option A, do I need to show that I made enough money for my self, siblings parents AND their children.
if I go with option B, what if this loophole has been sealed and they might say you can't petition for your ex-spouse for what ever reason?

Any help will be greatly appreciated.
