I looked and didn't find my specific answer.. I was looking to see if there is a "expiration date" on the I-134 and its evidence. Reason I ask is both my bank and emplorer stated they need at least 2-3 weeks to pull up my history with either of them and the date on the request would be today.. So I don't want the embassy to think that I pulled my info too far in advance.. make sense?

Best option is to contact the consulate. I e-mailed them (Rio - Brazil) to ask and they said it's good for a year. However, in the instructions they sent me (which are not updated, by the way), it says they're good for 6 months.
