LLC in Wyoming Owning Property in Other States
I presume you do not own the datacenter, but only use its services to run your servers, as an example. Whether this alone creates nexus for your business in the state where the datacenter is located would be a good question to ask a corporate attorney (preferably practicing law in that state), however in my opinion it's quite unlikely.
As far as taxes go, LLC is not taxed as a separate entity, but instead passed its profits and losses to its owners. I know taxation for international members of the LLC is a bit different than that of US members, however as far as I know you are taxed in the US for profits received in the US, so if your client base is Canadian in nature you would certainly be subject to taxation in Canada.
In other words, on all issues of taxation its a good idea to consult a CPA knowledgeable in US-Canada taxation question.
