Hey welcome to the forum, devilpup19.

I think these people have given you about as much advice as can be given under the circumstances, and I'm not going to add to but rather to suggest...
What about consulting a qualified immigration solicitor, for one?
And if you have tapped into the online gaming community, are there resources there as well for you?
Just saying there are other resources for immigration & gambling & tax advice out there, beyond this community.
We used to have a regular forum member who is/was, IIRC, a professional gambler along with her husband, but alas she hasn't been active now for more than 2 years. I think they may have had some other proviso, however, that permitted them residence here in the UK.
