I have heard of a few people having 2 (and even 3) working holiday visas even though the rules state you can only have one. I had mine 7 years ago now and am thinking of applying for another one but I want to know what the risks are and if I am unlucky and get refused what the consequences be. Unfortunately I have a very very uncommon surname so if they decide to look my name up on their system and Im still on it it will be very easy to spot me on there. I know the states can apply for more than one WHV but the UK are sadly stuck with a one per lifetime limit
