Are they taking applicants from outside US?
and is it a specialist role that you're confident a non-US resident is the only person that can do it?

If not, don't bother, the H1B system is still recovering from the terrifying raping that the Bush administration gave it. Astoundingly difficult for a company to get one for a new employee.

The listing was on a website, and wasn't specific about International applicants
I'd say it's a fairly specialist role, the industry isn't that large. All things to take into consideration though, so thank you for your 2 cents.

not trying to put you off
I've no real idea how specialist what you do is, so you might have no problems. The issue has been (historically over the last 10 years or so) that a really high proportion of H1Bs go to programmers from the Indian subcontinent who are highly skilled but will work for half the salary of US programmers. At last count there were only about 50,000 to 100,000 H1Bs available per year. Unless Obama has repealed that particular restriction.

Not wishing to undermine or devalue your excellent advice
But "terrifying raping" gave me this morning's biggest officelol to date, and I thought you should be told.
