US-UK

Also don’t claim you didn’t know any of this. You knew well in advance, as is clear from the first post in this thread 
 
 

So it wasn't really a hole but a combination of not doing research + deciding to immigrate even though their child couldn't as well.

Many immigrants face the same “hole”. Your in-laws had legal options. There were legal choices. Please don’t try justify breaking the law.  You are incredibly lucky that she is a minor or she would have a ten year ban from the US, and it would all be the fault of your in-laws making bad choices. 

That is work. Even if unpaid. Her sister could, and should, have hired a (legal) caregiver if she needed help.

Aside from the timing to get the visa, please consider how difficult it is for any woman to find an OB to take her as a new patient so late in the pregnancy which, in your case, would probably be even harder given increased liability risk for the OB (for a variety of reasons) as a result of her ex-US prenatal care. Also think about the cost of a delivery in the US and be sure her insurance (and insurance for the baby) is well in place before she sets foot in the US.

Moving across the country is a little different. Most people leaving their homes permanently —- or at least for the duration of AOS— would need to quit a job, break a lease, sell their car, close bank and other accounts, pack or sell all of their belongings, say goodbye to friends and family... 
 
I personally can’t imagine the cost and aggravation just to replace my clothes, shoes, makeup, etc. if I packed to go somewhere for 90 days and ended up staying 6+ months.

You mean... he needs to get legally married in a way that is recognised and accepted as legal by the US government and more specifically by USCIS? 
 
Marriage laws in Pakistan have no bearing in this discussion unless the marriage happened in Pakistan. It didn't - it happened, essentially, "online" which is what is causing this mess.   "Registering" it will not solve this issue - OP's friend going to Pakistan (or whatever 3rd country, since apparently OP & friend are convinced that OP isn't "allowed" to go there during his Green Card years) and getting properly legally married while physically in the same place as his wife - WILL solve the issue.

What the lawyer did not tell you is that you would still be responsible for gathering all the documents, and then their paralegal would fill out the forms for you.  Hiring a lawyer is a personal choice, but with a simple case, it is usually better to save the money and do it yourself.
 
Good Luck!

There wouldn’t be much, if any, love if it required not working, not traveling, potentially not driving, and not having my clothes and shoes... so it’s a good thing the OP is not marrying me (and also the reason we went for an EB1 rather than an Elvis wedding in Vegas).

Please please please do not adopt a child to increase your chances. Figure out where this relationship is going, before bringing an innocent child into all of this. 

Pretty sure Ryan is not Pakistani.  Apples and corn.

Obvious solution is for his Sister to move her wedding date.

Don't you know to never ask a woman her age and does it matter? I'm 21 years older than my husband and my husband didn't have any issues. Period.
 
You can look at my timeline to see the dates.

If your looking for FACT, then I recommend finding your own evidence by reading relevant documentation issued by DOS, only then are you able to confirm it as fact, other than that, your only getting people’s interpretation of the requirements. 
 
And while you might think it’s funny, yes, I firmly believe that child support is paid to support the child and that it’s reallocation and use to support a new spouse as part of the immigration process is morally wrong and I’m pretty sure family law courts would agree. 

Attorney Cann might consider reading a Warriner’s and running spellcheck on her professional website.
