Time Period outside of US on Green Card

[SanjayPita]

Hi, I am on Green Card and lately I am traveling to India alot due to my personal reasons.

 

Is there any rule for the minimum time period one can stay outside of US in a calendar year without risking Green Card?? 

 

Below is the time period during which I will be on vacation in India.

 

Vacation 1st 

Jan 09, 2015 - Feb 28, 2015 = 50 Days

 

Vacation 2nd

Sep 19, 2015 - Jan 26, 2016 = 129 Days

 

Prior to the above mentioned time period, I never had vacation more than 3-4 weeks. 

 

Please help and advise.
