关于头两次给两年，第三次给一年的规定 pursuant to 8 CFR 223.2(c)(2), a permanent resident who, since becoming an lawful permanent resident or during the past five (5) years, whichever is less, has been outside of the U.S. for more than four (4) years in the aggregate, will be issued a reentry permit with validity of only one (1) year from the date of issuance.

考古了一下，如果想保绿卡，但是长期回中国居住的话，要做以下的事情：
1，每次离境不要超过6个月（无论跨不跨年），最好不要超过3个月。
2，如果做不到，就要回去前申请回美证，需要等候3周去打指纹，然后就可以离开了。
3，回美证第一次可以管两年，之后只能管一年，就是说需要每年回美国一次。
我的理解对吗？
另外想请教下：
1. 是不是申请了回美证就不用担心绿卡入境时被盘问了？也不影响将来入籍？
2. 有没有限制回美证最多可以申请多少次？ 还是只要年年申请就没关系？
多谢！

这个时我说的第一条，最好在美国住够半年。
目前看如果回去就做不到这一点，这样就需要申请回美证了。
thanks a lot!
