intent to permanently live in US

This is a factor based test, not solely based on time abroad.  If you have a primary residence, bank accounts, spouse and children in US, esp when your wife works in US, and file your tax return etc, chances are you will be okay.

Abandoning Permanent Resident Status

You may also lose your permanent resident status by intentionally abandoning it. You may be found to have abandoned your status if you:

• Move to another country, intending to live there permanently.
• Remain outside of the United States for an extended period of time, unless you intended this to be a temporary absence, as shown by:
  • The reason for your trip;
  • How long you intended to be absent from the United States;
  • Any other circumstances of your absence; and
  • Any events that may have prolonged your absence.
  • Note: Obtaining a re-entry permit from USCIS before you leave, or a returning resident visa (SB-1) from a U.S. consulate while abroad, may assist you in showing that you intended only a temporary absence.
• Fail to file income tax returns while living outside of the United States for any period.
• Declare yourself a “nonimmigrant” on your U.S. tax returns.
