Yes I have done the CPE, I obtained my Vet license last July.
Are you a UK or Belgium citizen? this will make it very easy for you.
you will need a work permit, you can obtain this when you get hired by employer. If you are a UK or Belgium citizen then you can come to the states without a visa and stay for 3 months. (Visa waiver program)

this will help you find job. also you can get a student visa to start with by applying for internship or residency. since you are RCVS you can get internship or residency this usually don't pay much 23-37 K.
getting a student visa is much easier and faster. work visa are limited to 50000 a year and take 1-2 years to get also cost 3000$ if you hire a lawyer. if you can come to US as student and then you can do the work visa after that while you are student.
I was thinking to register with the RCVS, one day I like to go and work in the UK. How come you want to come to the US? isn't UK a good place to work and live?
