Let's go to the USA with Miss Yoko

The worse part

1. Preparing your petition (for us it was around 2 weeks)
2. Sending the petition to the Service Center.
3. Receiving the Notice Of Action 1 (1 week)
4. Receiving the Notice Of Approval 2* (between 2 months and 6 months)
   It's the longest and the worse part.
   Why?
   'cause as soon the Service Center will receive your petition, they will just put your file on a rack. And then your petition will be not processed before all the petitions received before yours are processed. During that time you'll hear nothing from the Service Center. It means that you'll not know if all is good with you petition or not.
   And by the way, there is 2 Service Centers they're in charge of processing that kind of Visa :
   
   • Vermont Service Center (VSC), it look like they process petitions pretty fast, within 2 months.
   • California Service Center (CSC), the slowest one, not less than 4 months.
   And you know what... (cry), our center is the CSC...
5. Service Center send your file to NVC (National Visa Center) (1 week)
6. NVC send your file to the U.S Embassy in your country (between 1 and 2 weeks)
7. Embassy send to you (the foreign fiancé(e) what they call : packet 3 (between 1 and 2 weeks)
   Packet 3 is the list of :
   
   • all the paperworks you'll need for your Visa interview
   • all the new forms you have to fill for your Visa interview
   When you'll have all done for packet 3, you have to tell the Embassy by sending them the checklist.
8. Sending the packet 3 checklist to the Embassy (if you prepared all before receiving packet 3 (all forms and instructions may be download in advance) 1 day, more if you're not ready)
9. Embassy send to you (the foreign fiancé(e) what they call : packet 4 (instructions how to process the medical exams) (1 week)
10. Embassy give you your Interview date. (it use to be sent at the same than the packet 4)
11. Interview. (between 1 or 4 weeks after the packet 4)
12. Visa in hand. (around 1 week after the interview).
