Hello, I've just started the process of filing the I-130 for my Vietnamese wife. I've been living abroad in the Vietnam for the past 6 years, and I'm confused by what exactly I'm supposed to do with the I-130 once I've completed it.

Am I correct in assuming I mail it the the Chicago address along with the relevant documents and fees?

Also, any other tips anyone can recommend to make the process go smoothly and quickly would be greatly appreciated.
