Is it possible to get I-134 outside of states???

Yes, You download it from here: http://www.uscis.gov/portal/site/uscis/men...00045f3d6a1RCRD

And can get it notarized at the US Consulate, or Embassy.

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% or (100% for military) 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.
