Like yourself, this is my first post, so a big hello to everyone also.
I emigrated from the UK to the US in April this year, and whilst I have found many differences from the IEE regs, it is not that difficult to become familiar with the NEC, (although some of the working practices take a bit of getting used to...).
I managed to get here on an E31 employment visa, which was sponsored by the (small) company I now work for, and the process from job interview to visa issuance took over 30 months. If your family are closely enough related to you, your visa could be issued far quicker.
I am fortunate enough that my employer holds weekly code quizzes, and gives us both time and payment for attending local electrical league seminars etc.
After 22 years as an electrician in the UK, it is a refreshing change to be working in dry weather, but you will have to get used to people saying you have an accent. (Which, being from Scotland, of course I don't!).
