Also if your wife is programmer, then probably she will find job too.
Her best, and probably only, chance to land a job in Poland is with her husband's company, and that is best arranged BEFORE they move to Poland. The chances of finding work for another company after she arrives are remote. She would be competing with Poles and other EU nationals. Very few employers would be willing to go through the hassle of hiring a non-EU citizen unless she has some serious qualifications and experience that are desperately sought after on the Polish job market, like SAP, HBase or high-level quantitative analysis skills, for example. "Ordinary" IT skills will probably not be enough. If she does have super-duper qualifications and experience, then I would question the rationale of moving to Poland at all in the first place, as she would be able to find higher-paying work elsewhere. Experienced SAP consultants make only $30 to $50 thousand a year in Poland, which is a great salary for Poland, but a lousy one on the global SAP market.
So if she comes along and since she isnt working, I dont know , it will be very different for her and there will one person earning, so thats my main concern,if she will like it or not, place is beautiful then back home but language barrier things can be difficult.
You right to feel concerned, It can be incredibly boring for her. To the point where it would put a strain on your relationship. I once taught English to the Swiss wife of a bank executive here in Wrocław, and she was bored out of her gourd because she didn't speak Polish, English or even proper German, so she could not make other friends. She lasted four months before going back to Switzerland. Also had a Korean student in the same situation because she didn't speak good English, and she didn't fit in with the local Korean ex-pat community, which is very cliquish and downright cruel to people who are not "in". In both cases, I was their only social contact whatsoever.
I assume your wife speaks English, so things won't be as desperate for her, but it will still be hard for her to fill her time with interesting activities with interesting people unless she is very outgoing, enterprising and adventurous. If she's shy or stand-offish, life will be very lonely indeed.
Unfortunately, I don't know much about the local Indian population. In any case, it's quite small, and there might not be many women like your wife to socialize with. I rarely see Indian ex-pat families in Wrocław.
However, when I was living in Chicago, I noticed that the wives of many of my Indian medical colleagues were horribly isolated and mal-adapted, and even arrogantly demonstrative of their unwillingness to assimilate or associate with the locals, even after many years of living in the States. It may be a good idea for her to occupy her time taking courses at the Wrocław Institute of Technology. Her chances of finding mental and social stimulation are higher there, and probably even better than in the workplace if she finds a job that doesn't pay very well. Most of the foreign ex-pat wives here in Poland are wives of high-level managers, administrators and executives, and they may not be very accepting of lowly employees.
