It may be worth the extra year wait to get your citizenship if at all possible.
You may be on shaky grounds with abandonment issues if you don't. As for citizenship, you need to be present in the country for even longer so unless you are going to fly back and forth a lot, there could be problems arising by upping sticks and moving back.
This is one of many examples over on the citizenship board.
