If you get a green card, you can travel outside the US and safely return. You must have misunderstood the 1 year rule. What it says is that a green card person cannot leave the US and remain outside for 1 year. Green card holders are permitted to leave the US just like everyone else. The only thing is unlike US citizens, CIS does not want green card holders to travel overseas and remain outside for extended periods. A green card holder will lose that status if s/he stays outside the US for one year or more.
