^Work Visa
IMO (based on actual experiences of my cousins & a sister) -- The companies that sponsor work visas for IT-related jobs are easier found in the Silicon Valley area. Also, Microsoft in Seattle & Apple in Cupertino are aggressive recruiters. The last 2 are undaunted by the expense and legalities of work visas. If Microsoft hires you, and your work visa isn't granted, it throws you to Vancouver; re-files in 3 months, & keeps on re-filing until you get it.
The tricky thing with work visas -- even if a company sponsors you & you qualify, the work visas are raffled off. There was that year 2009 (2008?) when the quota was 65thou work visas & only 36thou something were filed -- so ang swerte ng applicants, no more raffle (my sister was 1 of them). That was the 1st time too that the period for filing of applications was extended. I do not know now what the statistics are. But I am sure you keep track of their employment etc etc statistics and have a good idea of how their economy is.
(No Comment ako, I don't wanna endanger my 10yr tourist visa. Hahaha)
The good thing about their work visa (it's good for 7 years) -- you "own" it. Meaning, if after a year you decide to move to another company, you use the same work visa.
My impression. (but I just vacation in NYC 3 -4x/yr., I do not seek employment in the US) -- is that if your IT expertise has a good finance &/or managerial accounting background, you'll have better opportunities in NYC. That is what my Ateneo batch mates who went to Harvard/Northwestern or whatever East Coast school for their MBAs say.
Also, it isn't that easy to live in Manhattan. Pricey.
For example, Mid-town -- A 40sqm studio costs $3thou (with doorman & concierge). With appliances, but unfurnished.
If you rent, the usual requirement is you must earn 50x the rent and you must have a guarantor within NYC who earns 80x the rent.
It's probably more reasonable farther away. But well, Mid-town is Mid-town, is secure & appears to be not flood prone, and snow is quickly salted/cleared away.
Of course, we hear of the rich & rich Pinoys who live it up in Upper East/West & stay on partying & whatever. Hindi ko pa na cheezmwaz how they go about it eh.
