N-600 does not require applicant to be 18 or under..just some conditions to be met by that age..and I know even EWI applicants that are in the US can claim .
 
As a back up plan, I would use the same evidence that was sent in for N-600 and IMMEDIATELY apply for a US passport….costs little, risks nothing and fast response. 
 
 

That is not accurate.  N-600K is for those under 18 years old, but N-600 is available to adult US citizens born outside the US, as long as they acquired US citizenship at birth from their biological parent.  From the N-600 instructions -- https://www.uscis.gov/sites/default/files/document/forms/n-600instr.pdf
 
"You may file this application if:
1. You claim to have acquired U.S. citizenship through a U.S. citizen parent and are now over 18 years of age; or
2. You are the U.S. citizen parent or legal guardian who has legal and physical custody of an adopted or biological child
(under 18 years of age)."
 
@Imani, ignore the posts claiming your cousin's daughter's process was wrong.  USCIS already definitively declared her a USC entitled to a certificate of citizenship.  N-600 is exactly the process for those no longer eligible for CRBA due to being over 18 years old.
 
BUT, if your cousin's daughter had asked here before going through the process, I would have recommended applying for US passport first BEFORE applying for N-600.  N-600 before passport was a risky approach.  Glad she was approved.  Unlike passport application, N-600 is a one-time deal.  If she had failed her N-600 attempt due to some missing document or some trivial reason, N-600 would never be available to her again.
 

wait time for the I-485 interview will depend on the backlog at the local field office, so check the uscis processing time for I-485 for your local field office.
Also, i recommend having the employer extend the H1B if possible ,until you have the gc in hand. the moment you use AP or EAD your H1 status will end and you will have no status to fall back on in case GC gets denied. there is still a risk just in case marriage falls apart or other eligibility issues are discovered so general recommendation is to stay in status if possible till the AOS process is complete.

interview location is unrelated to the service center on the receipt. your file will eventually be transferred to the local uscis field office for the I-485 interview. field office depends on your physical address that you put on the application. you can find your field office by entering your zip code on this page

Assuming they do not marry and their Mother petitions them 12 years or so from now, 25 years through you?

I’m sure everyone petitioning siblings would love it if it were only 3-5 years. 
 
It’s 20+ years for the sibling category 

Her petition for her siblings is insurance. Never hurts to have multiple petitions.  Sibling petitions take about 20 years...maybe longer.

What do you mean "quirky"?
Do I look quirky? 

The F2A spouse visa process takes years.  You cannot wait it out in the US.  ESTA visits are only for 90 days max, and you are not allowed to work.  You may apply, but you will likely be denied.  Make sure to be truthful about the B2 denial, so you do not jeopardize your F2A process.
 

~~ Topic moved from Ir1/CR1 forum to Tourist visas forum ~~
 
Applying for a B2 while ESTA eligible is a gigantic mistake. ESTA is gone, if not forever, for many, many years. Added to that is a strong immigrant intent demonstrated by a pending I-130 for an F2A visa. Looks like she’ll have to visit you in Netherlands or you meet in a third country.

90 days wasn't long enough?  You can apply, but the denied B2 will, likely, trigger a denial.    Had you asked us, we would have warned you before applying for the B2.  You'll now have to meet outside the US.

The best case scenario for him is to keep in status, so the F1 is what he is on, otherwise he is solely reliant on adjusting through marriage. So I see where the Lawyer is coming from. 
 
Obviously not everybody is able to take the best scenario.

I also think that the advice to stay in school is meant as a safety net for your husband, so he can remain in legal status in case his AOS is denied or you divorce.  But if you two believe those are unlikely, then there is no reason for him to stay in school if he doesn't want to pursue further education.
 

I think there is a good chance you will not be allowed to enter if you try to use your existing F1 visa. based on the information you have provided there are several red flags that CBP would be able to notice
 you never attended the Master program. your explanation of switching to a language school seems quite odd. for getting admitted into a school, demonstrating english proficiency is required usually via TOEFL. how did you get admitted into the master program without proving the language requirement. you failed to maintain the attendance in the language school. the school was required to terminate the SEVIS record once you stopped attending the school  to ensure compliance, so its safe to assume it was cancelled. the explanation that you could not come back because of lack of funds actually goes against requirement of the F1 visa that you had committed to i.e  to demonstrate sufficient funds before starting the school.  
Based on the above i see problems entering on the existing visa, also based on the history its unlikely you will ever be issued another F1 visa.

Thanks for your comments. Separate I-130 process will take another 2 years as per the backlog. It is impossible to leave him alone as his is a minor (16 years old). Are you suggesting that he should apply for a student visa simultaneously with I-130 from one of the parent after LPR?
Many thanks for your guidance. 

He cannot immigrate with you; IR5 does not allow derivatives.
 
Once you enter the US and activate your LPR status, you will have to file a petition for him. It is critical that he remain unmarried.

I suppose the first thing to do is find out what happened to SERVIS. 
 
Will it look odd absolutely.
 
Will you be quizzed about it, I would think but no way to know for sure.
 
Are you going back for language or your Masters?

I think neither DHS nor USCIS is going to like the fact you never did masters you got your F1 visa for. Language school is always suspicious in this situation. You may have issues reentering US and or adjusting status.
 
You not having funds to study hurts your case and doesn't make it any strong.

Today when i spoke to the rep she confirmed my new address on file and that the letter was sent to the new address. What arrived though was only the SSN card w/o the EAD. 

did you use a lawyer by any chance? 
if the G-28 is filled depending on what was checked on it, It could potentially have been sent to the attorney address.
