Hello, I from russia (sorry if english bad) I live in Grozny Chechnya, Russia. I not able to add republic or city to my location. Can some body please help?

There's nothing you can really do about it, there's a lot of missing options for the cities in general. You could try to request it to be added through the support hub I guess, but the locations haven't really been properly maintained in years, and at this point I suspect it's more likely that the City field is removed entirely than anything being added to it (tbh I also just don't know why you'd want to tell everyone what city you live in, so if it were up to me I'd just throw it out).
