Im from UK as is my estranged wife who still resides there. Is it possible for me to get a divorce in Nevada?

Yes, it is -- but depending on facts you do not reveal, it may or may not be possible to resolve all issues in that divorce. Status (married or not married) goes wherever either of you go, so once you have been here for six weeks, you can file for divorce in Nevada.  See: http://willicklawgroup.com/grounds-and-jurisdiction/ You may, or may not, be able to resolve issues of property division, child custody, visitation, and support, alimony, etc. -- depending on whether any of those things are relevant, whether your wife makes a legal "appearance" in the action, and other matters.  See the article entitled "The Basics of Family Law Jurisdiction" on that same web page. After you have done some preliminary reading, I suggest making a consultation appointment with this or another family law specialist firm to go over your particular facts, circumstances, and options.
