Hey guys, I wrote this script 16 months ago and I haven't tested it for a long time, things may be changed now. So that I cannot provide more insights/solutions for what you mentioned above. Please refer to others' replies. Good luck to you all.

One question, is there some place that refers to this script? since these days the replies become more than ever before.

I just randomly came across this gist while searching ais on github lol.. Thanks for sharing :)

The reschedule(date) method doesn't seem to work. Did anyone write a functional version? Appreciated it.
I modified the original script and included logging: https://gist.github.com/Svision/04202d93fb32d14f00ac746879820722

@Svision I saw an implementation of @yaojialyu's gist here: https://github.com/uxDaniel/visa_rescheduler

Lo único malo es que el servidor lo bloquea a uno por entrar mucho :(
Yo Hice un boot también, busco la manera acceder a api importando request, logro solo iniciar sesión, de ahí no he pasado pasar. Alguna forma de guardar hacer request.Session() y que no se pierda el registro cuando le hago peticiones get a la página de appoiment?

Hi @yaojialyu , can you tell me what is number 108 for in the DATE_URL and TIME_URL please?

Hi guys, I see that the APIs does not work if we call them from the codebase. Have the US Gov made changes in the server to not accept APIs?
