There are plenty of foreigners working in Dublin so you won't be alone BCAIinfoSys! I knew a guy who worked for IBM years ago and he loved the place and was well paid. Even though that was in the 80s I doubt if their ethics have changed. If you like socialising you won't be disappointed, though unfortunately we have a Nazi for a Justice Minister and he has curtailed licensing hours for nightclubs, and most of them close now around 2.30am. City centre bars are good and plentiful, and open till around 1.30, so the club scene isn't as good as it could be. There are some good ones, but a lot of people won't pay admission just for an hour of extra drinking time.
Accommodation can be expensive, so most people share. I haven't got any figures to hand, but houses in the suburbs usually start around €400 per person per month. . . that is MINIMUM, and the closer you get to the city centre you'll pay a lot more. If you're talking about IBM in Ballsbridge, unless you have a lot of money to spend, forget accommodation there, it's one of the most expensive parts of the city, though there are good transport links to some cheaper suburbs. Cookstown would be a lot cheaper, though you'd be a good distance outside the city centre.
Eating out can be expensive, and an average meal with wine would set you back €50 per head, though most restaruants do an early-bird menu at around half that, which runs till 8pm. If you're really on a budget there are plenty of fast food restaurants which cater for most tastes. It's just a matter of finding your niche! You may have seen the list published last week ranking the cost of living in different cities. Dublin came in at no 14 I think, practically equal to New York. It's a cost-of-living index which companies use to grade expenses, etc.
On the whole most foreigners assimilate well, particularly English speaking ones. There is of course a certain amount of racism, but this is rarely directed at Americans, though you get the odd loudmouth who likes to blame ordinary Americans for the war in Iraq.
I'm not trying to put you off, I'm just being realistic and pointing out that Dublin, like everywhere else, has its bad points as well as good. Overall it's pretty safe and a very pleasant city to live in. The mood is generally relaxed, though a lot of people complain that it's not what it used to be. Partially true, but you'll find plenty of opportunites to meet people and make friends. People are generally interested in foreigners and you'll have no trouble making friends if you want to. One complaint I hear over and over again from foreigners living here is that Irish people never invite them into their homes. This is very true: most people socialise in pubs, clubs and restaurants. Continentals find this strange as they ususally invite people round to their houses for a meal. There is a complete ban on smoking in the workplace, and this includes pubs. It hasn't made a significant difference to them, though more people are socialising at home because of this, so the continental culture may creep in.
As long as it doesn't rain the climate isn't bad at all, and it's rarely either too hot or too cold. If you come I reckon you'll enjoy your stay. Most people who do enjoy themselves, and the city can have a great buzz to it. It's has the atmosphere of a big town rather than a city, yet it has practically all the facilities of a large city, and it's the kind of place where you can't really do ANYTHING anonymously.
Despite things you may hear to the contrary, the city centre is very safe to walk around, certainly during the day and even at night. Like any city you need to take the usual precautions, just don't look like a victim. There is the odd shark who can spot them a mile away. I walk everywhere in the centre at weekends and only once have had any trouble in 30 years. There are the usual no-go areas of course, but you'll have no need to go near any of them.
Public transport isn't as good as most European cities: there's no metro, and it's mostly buses, though there is a suburban railway along the coast and a brand-new tram system, though unfortunately it is only on two lines out of the city centre. Just don't expect anything to go by the timetables. Taxis are plentiful. Not dirt cheap, but affordable if you're on a budget and you're sharing.
Any more questions just ask. . .
