Exactly, AnnaC...always the helpful angel!!!
I went through what you just went through a year and 28 days ago exactly!!!
All you do now, after you're married, is send in the AOS papers...Form I-485 PLUS all the documents it asks for to support...the I-864 is an affidavit of support, plus you need to send in last year's IRS forms, bank letters stating what you have (if anything) employement letter stating how long you've been there and how much you make, your marriage certificate, copies of her passport and her son's where the visa was granted, etc.
You need to make sure you include ALL the paperwork they request...YES, it's time consuming...but all worth it!!! Don't worry too much about the 90 days...as long as you're already married, they are somewhat lenient about the deadline...Oh, DO NOT forget to include either a personal check, Money Order or certified check from the bank for the $1010...that includes the EAD (permit to work) and travel permit...You really do not need this last one...the Green Card will probably arrive even before you get it...but it's free if you do it all at once...so no harm done....
We sent it in later than the 90 days, after a month or so of receipt we got an appointment letter for his Biometrics (fingerprinting) schedule for a month later, and I'm very happy to say my husband got his GC in just a few months, 3 weeks exactly after he went for his biometrics...
As a matter of fact, he got the GC BEFORE he got his Driver's license... which we had applied for LONG before we did the AOS...it just took forever to receive it in the mail!!!!
About the social security...you can go RIGHT NOW and apply for one...all you'll need is her passport with the visa stamped on it, she will get her card in less than a month...it will say something like 'not authorized to work' until she gets her EAD...but that shouldn't take long...just a couple of months...in the meantime she can get used to life here in the USA and getting around, etc, etc.
Anyway, you can do all that together with her son's info...don't forget to include him in there...
You WILL find all the info you need and more on the links Anna and cobraboy provided...it's the BEST LITTLE WEBSITE ON DOMINICAN IMMIGRATION IN THE WORLD!!!!
Oh, one more thing....I know some people are trying to help...but really, they don't know anything about this...UNLESS they have gone through the process themselves....
DO NOT GET AN ATTORNEY...I REPEAT...DO NOT GET AN ATTORNEY...
MOST attorneys DO NOT KNOW anything about Dominican Immigration...trust me...it's like NOTHING in the world...
On DTTUSA we even have the chief Consul in DR, Mr. Bent, posting answers to common questions people have...it's been a tremendous help...and thanks to those questions he's been able to implement GREAT, AWESOME changes to the way things were done at the Consulate in DR...
