Copies are fine, but better yet, get simple IRS transcripts.
NOTE IRS has the originals you have copies of the returns.
One thing about I-134, the directions included with I-134 are very old, USCIS has no reason to update them since USCIS has no application for that form.
The consulates tend to treat the I-134 like a mini-I-864 as so prefer the same financial evidence as the I-864.
In our case this what the I-134 included.
- I-134 signed and notarized.
- SIMPLE Tax transcripts from the IRS for past 3 years, (Redundant for the (1040,W2,1099) but are free from the IRS http://www.irs.gov/faqs/faq1-6.html
- Photo copy of IRS form 1040, and W2s for past 3 years (Not necessary if you provide the transcripts)
- Letter from my employer stating annual salary, job responsibility, and that is full time, on company letterhead.
- Photo copies of past month or so of pay stubs up to a few weeks before the interview.
My income was well above the povertyline so I did not include any asset data (LIKE BANK STATEMENTS or property values).
If your income exceeds 125% of the povertyline when counting yourself, prospective immigrant and any dependents, then don't bother with assets (401K, Bank balance, Stocks etc..), it is just extra un-needed data to provide, the consular officer is most concerned with INCOME.
This is what I have ready for the Affidavit of Support.
Is this enough information?
* Signed and notarized I-134
* Statement from bank officer confirming Date account was opened, Total amount deposited for the year, and present balance.
*Statement from my employer stating when I started the job, my slary paid, and that the job is permanent, and I am an employee in good standing. ( I make $47,000 per year and have no dependants)
* Copy of my 2006 tax return
* 6 pay stubs dating back to when our petition was received by USCIS up to the present time
* Copies of stock certificates I own ( I recently became a business owner in 2007. I have not yet done a tax return for 2007. Stock is worth approx. $38,000)
* Copy of my 401k earnings ( I don't think this is needed, but I wanted to send it for additional info)
