US Visa Auto Rescheduler is a Chrome extension designed to automatically reschedule US Visa application appointments to earlier dates for AIS en-CA users. This extension supports the en-CA language and is tailored for U.S. Nonimmigrant Visa Applicants. Upon installation, users are redirected to the AIS US Visa home page to set up the extension. By activating the script and providing user email and password, the extension can auto-login and manage appointment scheduling efficiently.

The extension offers features like enabling auto-booking for earlier dates, setting frequency of availability checks, selecting a target date, and a reset button to revert settings. It operates by decreasing credits only when successfully securing an earlier appointment, without utilizing credits if no suitable date is available.
