I got my green card for 20 yrs but I am outside US now. Can I still apply for naturalization?

I've had my US green card for 20 yrs but never apply for naturalization. 6 yrs ago, I took a job in US for a US company. This job requires me to station in China. I go back US twice per yr and stay 1 or 2 wks each time. Am I still qualified to apply for naturalization to become US citizen?

If you have not been out of the U.S. for a continuous period greater than one year, it looks as if you should be eligible. Welcome.
