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:  Quote “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.  …” End Quote  So, I posted on Brock and here.  Seems there’s been quite a change at Vancouver.

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]:  Quote “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.” EndQuote
So:  (1) only one visit is required, (2) you must book through Vancouver.CLN@state.gov (not through the online calendar).

Quote“Thank you for contacting us regarding renouncing U.S. citizenship.
Please do not reply to this email.  This inbox is not monitored.
Renunciation of U.S. citizenship must 1) be taken in the presence of a
diplomatic or consular officer; 2) be taken outside the United States;
and 3) be in the precise form prescribed by the Secretary of State.  It
is an irrevocable action that cannot be reversed.  Should you choose to
pursue renunciation of your U.S. citizenship, you will have to complete
form DS-4079 – Request for Determination of Possible Loss of United
States Citizenship and come to the Consulate to sign an “Oath of
Renunciation of the Nationality of the United States” and a “Statement
of Understanding”.  These documents form the basis for the Department of
State’s decision regarding the U.S. citizen’s request to renounce
citizenship and are enclosed for your information.
Please review these additional documents before scheduling an
appointment:  Renunciation of U.S. Citizenship (
http://travel.state.gov/law/citizenship/citizenship_776.html
<http://travel.state.gov/law/citizenship/citizenship_776.html> ), Right
of Residence in the U.S. (
http://travel.state.gov/law/citizenship/citizenship_777.html
<http://travel.state.gov/law/citizenship/citizenship_777.html> ), and
Dual Nationality (
http://travel.state.gov/travel/cis_pa_tw/cis/cis_1753.html
<http://travel.state.gov/travel/cis_pa_tw/cis/cis_1753.html> ).
On July 13, 2010 the Department of State implemented a fee of $450 for
administrative processing of formal renunciation of U.S. citizenship.
This fee is payable in either U.S. or Canadian dollars or by major
credit card on the day of your appointment.
Once you have all forms filled out and you have gathered the required
evidence, please email vancouveracs@state.gov
<mailto:vancouveracs@state.gov>  to schedule an appointment.  Your email
should indicate that you read this email and that you have filled out
all your required forms and gathered all required supporting
documentation.  Please include a contact phone number in your email.
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.
At the time of your appointment you must bring:

documenting a prior relinquishment of U.S. citizenship (usually a
Canadian certificate of citizenship with the date you became a Canadian
citizen).  This is not required if you are currently a U.S. citizen
renouncing your U.S. citizenship.  Please see this link to learn about
the difference between relinquishment and renunciation (
http://travel.state.gov/law/citizenship/citizenship_778.html
