How it works

One quiet companion for the appointment portal — contribute while you check, benefit when others do the same.

  1. 01

    Add to Chrome

    Click Add to Chrome, then finish the short developer-mode install.

  2. 02

    Visit the scheduling site

    Log in to USVisaScheduling and check posts the way you already do.

  3. 03

    Slots stay current

    Availability is shared so the community can react the moment openings appear.

Install on Chrome

Google only allows one-click install from the Chrome Web Store. VisaBook installs from this site in a few steps.

  1. Click Add to Chrome above — your browser downloads visa-book-extension.zip. Unzip it.
  2. Open chrome://extensions and turn on Developer mode (top right).
  3. Click Load unpacked and select the unzipped visa-book-extension folder.
  4. Open USVisaScheduling.com — the toolbar icon confirms it is active.
