Similar to all other large UK bookmaking groups, since the arrival of online betting and the general globalisation of sporting events Stan James Group have various offshore divisions and companies registered in various ways in various countries. However the Stan James Group is still at its roots essentially a British bookmaking company which has a long history of honest trading.
Many years ago you would have only found Stan James family members and employees trading as pitch/rails bookmakers at horse and dog racing tracks in UK. The next step was to open a chain of High Street betting shops in UK and to branch out into sports betting. They have always seemed to have a flair for betting innovation and 'pioneering' and were one of the first firms in UK to introduce regular handicap betting markets. They have often been the first large global firm to take a chance on opening a betting market in the more obscure and minor sports, perhaps hence their apparent willingness to give pool a fair crack of the whip.
They are not quite yet in the same league size-wise as the big boys such as Ladbrokes and William Hill but they are a multi-million pounds sterling group which is certainly right up there in at least the second tier of betting giants.
One of their divisions happens to be a sponsor of The Candian 9 Ball Tour.
As regards the USA authorities position on the current legality of online betting and the bank transfer of funds related to such betting in and out of USA, this has been discussed many times in the IPT threads and elsewhere on these boards. It's a bit cloudy but those AZB'ers without any banking facility outside USA may well experience great difficulty in betting with Stan James or any of the other betting groups online divisions. This type of problem for citizens wishing to bet online can only be fully rectified by action on the part of the Govt of USA. Presently that Govt seem to have no inclination to encourage the freedom of USA citizens to make their own decisions as regards where, when and with whom they place any online bets. Whether that policy is inspired by fundamental morality issues or by vested, protectionist interests of USA based betting organisations is not clear. What is certain is that all the online bookmakers view the USA as a huge potential online market which they would love to be able to legally service.
Hope this clarification helps but as usual at the end of the day these are just my personal experience, observations and two cents worth
