Thanks for the tip. I'll definitely check with the embassy first!
Isn't it 3 times of poverty level if it is US citizen applying for the spouse?
 
------"Item Number 10. Total Value of Assets. In order to qualify based on the value of your assets, the total value of your assets must equal at least five times the difference between your total household income and the current Federal Poverty Guidelines for your household size. However, if you are a U.S. citizen and you are sponsoring your spouse or child age 18 years of age or older, the total value of your assets must only be equal to at least three times the difference. If the intending immigrant is a foreign national orphan who will be adopted in the United States after he or she acquires legal permanent residence, and who will, as a result, acquire citizenship under section 320 of the INA, the total value of your assets need only equal the difference."

I'm curious as to how he had planned to "send it directly to a US agency"......Honestly, it sounds like he just doesn't want you to see it......good luck.

You could suggest he seal it in an envelope with a notice of it being opened by embassy only. I know of course you could still open it but maybe he would feel a little better in regards to his privacy. 
 
A W2 doesn't show you filed taxes...only that you received a W2

A copy of the latest tax year's tax return is a requirement for the I-864. The I-864 will not be accepted without it, and therefore won't qualify as a joint sponsor. As such, they would issue the visa or not based on the petitiooner's I-864.
If denied at the interview, you would given a 221g requesting a satisfactory I-864 to be sent (no second interview required).
 
Edit: Also, tax returns show past income. You really should be providing evidence of his current income as well, typically pay stubs and an employment letter.

Only US citizens are guarantee entry into the US.
 
You could be admitted or you could be denied entry.  It depends on your circumstances.  Most people visit with no problems.

I have a similar question.
I already have a ten-year tourist/business visa which means I can go to American for short stay.
Right now I live outside US with my husband and I have a pending CR1, waiting to get approved so we can move back to America. 
So if I have a legitimate reason to visit America for tourist/business intention, and can provide necessary documents(like company invitation letter, flight return tickets etc) to prove it to the custom officials, would I still be denied at the border?
