You could apply for membership of The Magic Circle in London.
There are already about 200 members from USA.
Every month an excellent magazine "The Magic Circular" drops through your letterbox and should you ever find yourself in London you can visit their HQ.
Their website can be found here:
Of course if you ever visit Ireland you will be welcome to come along to any of the Irish Magic Clubs and all the info for those can be found at
Hope some of this helps.
It is great that there are guys like you who just wish to belong to societies, where they can meet other magicians and give their support and help where required and needed. Often it is these "silent" members who with their subscriptions, physical help and presence are the real mainstay of a society.
