You will need to go through CCUSA or BUNAC then go to the Camp Fair which is in Feb/March in various places around the UK and apply directly with the camp at the fair. You will get your USAG Safety Certification in your orientation week at the camp. It does not matter what BGA coaching qualification you have as you will have to be there for the whole summer you will automatically join the coaching degree program offered at the camp. By the end of the summer you will go through level 1 and hopefully receive your qualification. You will certainly be in the minority in regards to coaches from abroad because the majority are from the US, however, this year there were two or three from the UK. Hope that info helps, if you have any more question let me know...
