You shouldn't have problems, but the real question is how long do you plan to spend in the U.S.? If just days or wa couple of weeks, you'll have problems convincing inspectors that you have not abandoned U.S. permanent residency. You should keep your domicile in the U.S., file annual income tax returns (you will be required to report U.S. & world-wide income earned), and keep current a state driver's license. You should consult with a U.S. immigration lawyer.
