I'm planning to relocate to the USA. Any Tips, advices?

Emmanuel,
If you are as fluent in English as your single sentence suggests, you should do very well here. There is an exploding Hispanic population in the USA and Hispanics have all the same computer and programming needs as other ethic groups. Being bilingual would be a BIG plus! Many immigrants from central and South America have found Nebraska a good place to live and raise their families. Several towns along I80 have had such an increase in Hispanic populations that they now comprise a voting plurality. It reminds me of the 1880-1920 period in Nebraska when large groups of Polish, German, Bohemian and Swedish immigrants moved to Nebraska and established or dominated entire towns (Broken Bow, Ord, Stromsburg, Clarks) where the primary language was their mother tongue. As the years passed the young learned English in public schools and while their cultural heritage remained, a large part of the communities blended, without losing their cultural pride. Sort of like the nightly news of CNN, ABC, CBS and NBC having a 'merging' effect on the English dialect. More and more, "American" English is blending into a single dialect and except for old folks living in Boston, Main, or Louisianna it is becoming difficult to tell, by their accent, which part of the USA folks live.

Good luck!
