I've been toying with the idea for the last few years and I figured it was about time to start asking questions about it! Here goes:

I'm a Senior-level .NET/C# programmer from the UK, with 7 years of commercial experience in industry and looking to work over across the pond in the big ol' USA! This is with a view to live there on a permanent basis.

My idea is to try and set up some interviews and go over there for a week to attend them, then I guess wait for responses in hopes they'd sponsor me for a working VISA.

I'd like to know is there anyone out there with any experience of doing the same thing? Was it difficult finding work? Is there anything I should know before embarking on this route? How long did the transition take?

Update:

Considering the down votes, either I've posted this in the wrong place, or people really don't like my query. If so, please shed some light.
