US Visa Rescheduler for Canada

A simple Python script for making US visa interview appointments in Canada

Update

• 🎉 The core functionality is still working (as of March 2026) according to users' report
• Gmail-related code might error out, but it doesn't block rescheduling
• Adopt this repo: this project is looking for a new maintainer, open an issue if you'd like to adopt it.

Features

• Automatically checks for available visa interview slots at your selected consulate
• Supports multiple consulate locations across Canada
• Configurable date ranges for appointment scheduling
• Email notifications when appointments are found or rescheduled
• Support for excluding specific date ranges
• Headless operation mode for unattended running
• Test mode for safe testing without actual rescheduling
• Automatic retry mechanism with configurable delays
• Support for multiple applicants in a single appointment

Prerequisites

• Python 3.x installed
• An existing US visa appointment booked on https://ais.usvisa-info.com/en-ca/
• Gmail account for notifications (optional but recommended)

Installation

1. Clone this repository
2. Install dependencies:

pip install -r requirements.txt

Supported Consulate locations:

CONSULATES = {
    "Calgary": 89,
    "Halifax": 90,
    "Montreal": 91,
    "Ottawa": 92,
    "Quebec": 93,
    "Toronto": 94,
    "Vancouver": 95
} # Only Toronto and Vancouver consulates are verified

Add a new .env file to the root of the project, this file will be used to configure parameters for the script. You can use the following parameters:

USER_EMAIL=""   # The email address for your https://ais.usvisa-info.com/en-ca/niv/users/sign_in account
USER_PASSWORD=""    # The password for your  https://ais.usvisa-info.com/en-ca/niv/users/sign_in account
EARLIEST_ACCEPTABLE_DATE="" # The earliest interview date you are looking for
LATEST_ACCEPTABLE_DATE=""   # The latest acceptable interview date
USER_CONSULATE="" # Use one of the cosulate names from above
GMAIL_SENDER_NAME=""    # Name of sender on email
GMAIL_EMAIL=""  # Sender email account
GMAIL_APPLICATION_PWD=""    # Use the app password you generated for application -- check https://support.google.com/mail/answer/185833?hl=en
RECEIVER_NAME=""    # Recipient name
RECEIVER_EMAIL=""   # Recipient email
EXCLUSION_START_DATE_1=""   # Start date for first excluded date range
EXCLUSION_END_DATE_1=""     # End date for first excluded date range
EXCLUSION_START_DATE_2=""   # Start date for second excluded date range
EXCLUSION_END_DATE_2=""     # End date for second excluded date range

You can add upto 9 exclusion date ranges. Each date range to be excluded using the syntax EXCLUSION_START_DATE_{i} and EXCLUSION_END_DATE_{i} where i can be replaced by numbers between 1 to 9.

Find a slot and book it automatically

python reschedule.py

See the script in action. Once you're satisfied with its functionality, set TEST_MODE to False in settings.py. For a headless operation, you can also set SHOW_GUI to False and allow the script to run unattended.

Note detect_and_notify.py is no longer maintained.

Caution

It may not always be feasible to reschedule an appointment multiple times. Therefore, it's crucial to use TEST_MODE = True for testing purposes and ensure the LATEST_ACCEPTABLE_DATE is genuinely acceptable to you.

Consulates other than Toronto and Vancouver are not tested.

Please feel free to report issues. PRs are welcomed and greatly appreciated!

One improvement I'm interested in is rewriting legacy_rescheduler using requests.

Special thanks

Huge thanks to @jywyq for adding the Gmail notification feature.

Huge thanks to @bsingh-kpt for (finally!) fixing the legacy_rescheduler in Mar 2025.
