in every walk of life though one may feel tht money is not the only thing tht is essential for life, at times it grabs our attention and dictates many things.
if u plan for a short stay like the way u r thinking now and execute in action also, i dont think it wld b tht much dificult. but wht happens in practical is..... first year/s goes in settling and exploring and doing the things u wanted to do for ur family etc...since everything is fine here and got adjusted to the comforts and dificulties, u wont mind extending ur stay for 1more yr and the life goes on. then the real problem comes in. u may miss many steps tht u r supposed to step in if u r in mainstream of IT especially if u r in development side.
if u r in other areas of IT, definately you may hav good experience over here as u get the chance to improve ur skills- like client handling etc...
but staying for short term is always the best thing.keep the contacts continue with the IT industry back home.
all the best for ur future.
