I second that. This is a very important distinction!Plenty of people are issued 10 year tourist visas. This does not mean they can stay in the US for 10 years. It means they can use the visa to enter the US for 10 years. Tourist visas usually allow for up to 6 months of stay in the US as a tourist, only. Tourists cannot go to school, cannot live here, and certainly cannot work here. Tourists are tourists.
Her visa expiring in 2 years does not mean she can stay in the country for 2 years. It means she can enter the country for two years. Her length of stay upon each entry is determined by the CBP officer at the port of entry, and should be noted on her entry stamp in her passport. If she has stayed past that date, she is now in the country illegally.

You should have:
1. Cover letter.
2. Filled out and signed (by petitioner) I-130.
3. Filled out and signed G-325A - petitioner.
a. Attach (with paperclip) a passport photo, and write petitioner's name on the back.
4. Filled out (doesn't need to be signed) G-325A - beneficiary.
b. Attach (with paperclip) a passport photo, and write beneficiary's name on the back.
5. Copy of marriage certificate.
6. Copy of one of the following:
a. Petitioner's US birth certificate, or,
c. All pages of petitioner's US passport.
7. Copy of certificate of naturalization (if petitioner is naturalized)
8. Check or money order made out to Department of Homeland Security - USCIS in the amount of $420.
9. If either of you were married before, include court certified divorce papers.
10. If either of you were widowed before, include copy of former spouse's death certificate.
11. If you want email or sms notification of receipt, attach form G-1145 to the front of this package.
12. Evidence of bona fide marriage.
This may include pictures, joint assets, joint bank statements, flight itineraries and/or passport stamps to each others' countries, chat logs, phone bills showing calls to one another, receipts from things that you have done together, birth certificates if you have kids, adoption papers for a dog, you name it. Anything and everything that can help to show that you are in a bona fide marriage.
This entire package should be organized, for example in a manila folder, or however you best want to organize it, but don't use a hole puncher!

Are you talking about the big, brown envelope given to him by the consulate?
That big, brown envelope is your entire case file, everything, from the moment of initial filing, until now.
He has to have this at POE - unopened, or he will not be entering the US.
If you're talking about copies that you guys have, those are usually not needed, but I would definitely keep everything with me just in case. Better safe than sorry.
