thanks Peter, these links are much more informative than the basic disclosure i was looking at,
it looks like i will need to contact phil embassy, first to confirm if they accept acpo and acro,
i read also at acro they say the certificate is normaly valid by embassies for 6 months, so i can make a start on the application maybe this weekend,a couple of misdemeanors in my youth but think should be ok,
one other thing , when printing an application form which is the right way, print both sides of paper? or single sheets ?
