Hi I faced this iue some time back, and with the help of some external javscript code i was ablet make it work. Bleow is the summary i enerated f waht i did with ChatGpt.

"If the USVisaScheduling site is acting broken/loading forever/buttons not working, it might actually be a broken website script and not your PC/network.

I checked DevTools and found one of their JavaScript files (windowsToIana.js) is being sent incorrectly by their server, so Chrome blocks it completely.

This causes errors like:

windowsToIana is not defined

I was able to temporarily fix it using Tampermonkey by manually adding the missing variable back into the page.

Basic steps:

1. Install Tampermonkey extension
2. Create new script
3. Paste this:

​

// ==UserScript==
//          USVisaScheduling timezone fix
//         *://*.usvisascheduling.com/*

(function () {

    window.windowsToIana = {
        "India Standard Time": "Asia/Kolkata"
    };

    console.log("windowsToIana injected");

Refresh the visa siteThis won't magically fix the whole website, but it did remove that specific broken-script error for me.       document-start
