No ones mentioned hassles one can get on cross border gigs. Luckily, in Toronto, we have a great person at Human Resources / Foreign Worker employment who has really helped us on numerous gigs, especially for those from the UK. Leave plenty of time for permits etc. The office here has had to provide validation for the High Commission in the UK - though this is not always requested, apparently it should be and it crops up at the wrong times.
