Vorrei visitare presto la Georgia e ho una domanda: i georgiani capiscono l’inglese se parlo con loro?

I would say most of the young people will understand

Georgians have strict rule and code of honour: never speak English unless it’s with somebody who doesn’t understand it. Now, that might sound like I’m bullshitting — but ask any genuine Georgian here and test the veracity of statement.
Now, a cousin of mine visited a few days ago and he could speak just English, but claims he was able to communicate just fine with everybody using sign language.
Mods — confirm to OP that I’m telling the truth.

no speako englisho

It depends. Young people? Yes they know english. People over 40? They will understand most basic words but most are no were close to fluency in my experience. Older generation knows Russian a lot better than younger one though.
