For a real general answer….

I have a friend who has been there numerous times on work projects. She loves it and hasn’t expressed any concerns. However 1) She’s fluent in Russian and has worked on dozens of projects in former SSRs and 2) on the project I worked with her in Ukraine, locals made all the arrangements for transportation, housing, medical emergencies, etc. and smoothed out every hassle that showed up.

I assume locals means her colleagues and associates, I suppose? Considering she speaks Russian and knows the folks is a big advantage for her as not too many people will take her for a ride.
Is russian the national language? or is there some other version of georgian?
Without knowing Russian, is it safe to come back to the hotel or home in the night? is the transportation good? specially at odd hours?
How does she go around Georgia?

The official language is Georgian, which is spoken by 71% of the population as their mother tongue (source), and is used as the national lingua franca in government, education, daily business, and the media. Russian is understood by many Georgians as a result of Georgia being a part of the Soviet Union (or Russian Empire prior to 1917) until 1991. City dwellers in particular are likely to understand Russian (source), and it should be fairly easy to navigate the country using Russian (source) if you don’t speak Georgian. Russian holds official status in the breakaway regions of South Ossetia and Abkhazia, alongside the local languages spoken there.

The Georgian and Russian languages are not related to each other at all. Russian belongs to the Indo-European family of languages (which includes English). Georgian doesn’t.

Thank you for the update,
any idea if the people can understand and speak English at all. Is the education and tourism at any level of English?

Any idea if I can take day trips to Batumi, Baku and Yerevan from Tbilisi?

Depends on part of Tbilisi. Business center – you will find more people who, if not speak English, at least understand enough for you to be able to communicate. Education-wise – just about everyone takes a foreign language for a few years in school. Many don’t care or pay attention. Many do. And they become pretty good at it. Older people generally will not speak or understand any foreign language (keep in mind, Russian is treated as foreign language by young generation, but all the old folks speak and understand it). Don’t go around speaking Russian if you don’t want to be beat up. And stay off the streets in certain neighborhoods late at night. In fact I don’t know which neighborhoods are safe at night. If you have to come home late, get a taxi and have them drive you to your place. It’s easy to get in trouble, but hard to get help and support.
Edit:
And I answered your last questions in the other thread.

After a tragic experience in Moscow, I was young then, now my family is very concerned, so I am trying to make sure I speak to others and make a fair judgement. Eta bandito is what i was told by the US citizen services to be keeping my eyes and ears open.

I spk to someone today at tbilisi, and he said with a little hesitation, Georgia is not Russia and not to worry.
This is exactly what I am worried.

However, I also spoke to someone from Yerevan and they said Georgia is full of bandits. In fact, I was told that when Armenia got hit by its catastrophic earthquake, the relief had to pass through Georgia and everythng good looted by the Georgians.
Not sure what the truth is….

Unfortuntley, I don’t see much of warning by the US Dept of State bulletin.

Do you know of any known or familiar taxi guy whether private or public that can be considered reliable that i can use their services?

Yes, sadly with the way the country got corrupted over post-soviet years.
I’ll make a few phone calls and see if I can find someone that has taxi business, or someone who knows someone. I still have friends and family there.
Your Armenian friend is quite biased, but I’m sure there’s some truth to his story. One thing to consider though – after that earthquake my father was one of many volunteers who went down there to help clean up the mess. It’s all stereotypes – not every Georgian guy is bad, and not every Georgian guy is good. Just use your best judgement while there.
I’ll let you know about taxi.
Where are you staying while down there?

Not yet decided. the principles of this company stay at the Marriot but till now they have not decided on the budget.
So I am to look for something at the economy to the medium price range. Staying at a hotel or motel does not bother me as long as I have my own room w attached bathroom.

Sammohanty, you don’t have to answer this, but I am curious how it is that you are always traveling to so many places. But I see your career is project management, so I guess you are going to different projects.

The Marriott in developing countries (or whatever category Georgia is in) tends to be very expensive, particularly compared to local rates.

Yes, I am in project management and Business development for IT projects working in a consulting capacity. With most projects being offshored, I have to travel. The co I work for is based out of UK.
Hoping the economy to stable so I can start looking for a permament role back at home and don’t have to travel overseas.
Travel for work is tough.
