Recieved a date for an interview in Vancouver, but it doesn't really tell you what needs to be brought so far I know this should probably be brought.

1. Passport
2. Proof of Relationship.
3. Marriage Certificate.
4. Money? Is there some charge?
5. Copies of paperwork filed.
6. Sealed Medical Results.
7. Passport photos.

Not sure about K visas, so
IT seems you are missing the DS something form... was it DS156K??? Don't know.
The charge is 100 bucks.... but then again I'm sure someone with K-Vancouver experience will jump in and tell you.
In any case.... good luck!!!!

Did Vancouver not send you the Packet 3 checklist? That should tell you everything that needs to be taken to the consulate for your interview.

I did a K1 so I know I received a different checklist, but you might also need a police certificate?

Len - the DS-156K is for fiance apps. He might need a DS-156 though

Ok I got the checklist I thought there was more to it than just that.

Good luck with your interview!! Let us know how it goes. I'll have my K-3 interview in Vancouver as well (someday).
