It’s been months since I’ve seen any availability for Vancouver appointments. Thanks to Cyal8rUS, who posted the following comment on the “About the Isaac Brock Society” page.
“If someone with authorship privileges would be able to blog this: The Vancouver US Consulate FINALLY has new appointments available for “other” ACS services. If you have been trying to book a renunciation appointment, get there quickly. …”
The Vancouver website says; “If you would like to make an appointment to renounce or relinquish your U.S. citizenship, please email VancouverCLN@state.gov ” So, I e-mailed that address a few minutes ago and got an immediate automated reply (very comprehensive with detailed instructions). Of particular interest is this paragraph [emphasis added]:
“IMPORTANT NOTE REGARDING APPOINTMENTS
If you arrive fully prepared for your appointment, we will likely
process your loss of nationality in one interview. If you do not have
the forms filled out or if you do not have all required original
evidence, you will need to return for a second appointment.”
So: (1) only one visit is required, (2) you must book through Vancouver.CLN@state.gov (not through the online calendar).
