Not trying to put you off, but H1B's are so difficult, mainly due to the small number available each year. I got one year's ago, but I'm not a dev. As far as I know it's not too late, particularly if the hiring company uses lawyers who have good connections at the USCIS.

If you're looking for dev jobs at companies that sponsor H1B, I noticed today in the Who's Hiring that some are offering H1B sponsorship.

Good luck, it's a arduous undertaking. Out of interest, what country are you from? There may be other visa types available to you. For instance, aussies get their own E3 visa which is essentially a H1B.
