After the pandemics some consulates are out of schedules since there is lots of persons trying to renew their visas. I always hear about some "slots getting opened" but when I try advancing my schedule I never found a free date. So, I decided to try to monitor these free spots. With that in mind, the easily way was to paste some script on browser console for "beeping" when a date that satisfies my conditions is available.

1. Adjust the script (filling the variable accordingly) for your needs:

• Fill your account number, that can be found on your url when logged into the scheduling system.
• Fill the code of the CITY you want to monitor. (I have just mapped brazilian one's)
• Fill the months you want to monitor in the format provided as sample ("2021-12", "2022-01")
• If your city has more than one option of office, you can fill the expectedOrg variable with the office code. (I have just mapped brazilian one's)

2. Login to the scheduler system (https://ais.usvisa-info.com/pt-br/niv in portuguese)
3. Go to reschedule and leave the page ready (to be faster) to reschedule you appointment. I suggest choosing a different city, so you can change right away after listening to the beep.
4. Duplicate the browser tab (you must duplicate the logged in tab), open a developer console, and paste the script. It will begin pooling the free spots based on the conditions specified and BEEP when it find one free spot.
5. Wait for the beep, and run to finish your reschedule.

To stop the script, enter the command stop() on the console and hit enter:

stop()

Just call the beep function anytime after pasting the code:

beep(1000, 0.5)

Just go to your developer console at your browser, and check the "Network" tab, when manipulating the options (selecting the city/office) you will see the codes on the request's urls.
