There are many non-UK pilots in Virgin, though I'm pretty sure all will have converted to a UK-issued ATPL on or before joining VS. Why you haven't received a reply I can only guess is down to the sheer numbers of well-qualified people applying to Virgin. I can only suggest that you mail them at
[email protected] to ask for confirmation that they have your application.
A thought: have you ever completed the online application procedure? I'm pretty sure that is now the primary (only?) way to get your application accepted. If you haven't done it, I suggest you do.
Big Junglie, I think PPJN has the current pay rates at Virgin. At worst they'll only be a few months out of date. Roughly speaking, on joining you will be on around £59k pa including variable pay.
