Permanent residents are free to travel outside the United States, and temporary or brief travel usually does not affect your permanent resident status. If it is determined, however, that you did not intend to make the United States your permanent home, you will be found to have abandoned your permanent resident status. A general guide used is whether you have been absent from the United States for more than a year. Abandonment may be found to occur in trips of less than a year where it is believed you did not intend to make the United States your permanent residence. While brief trips abroad generally are not problematic, the officer may consider criteria such as whether your intention was to visit abroad only temporarily, whether you maintained U.S. family and community ties, maintained U.S employment, filed U.S. income taxes as a resident, or otherwise established your intention to return to the United States as your permanent home. Other factors that may be considered include whether you maintained a U.S. mailing address, kept U.S. bank accounts and a valid U.S. driver’s license, own property or run a business in the United States, or any other evidence that supports the temporary nature of your absence.
基本 上的说法是六个月以上， 一年以内， border control 可以要求你证明你有呆在美国的意愿。 一年以上， 基本进来以后要去移民法庭辩解了。
啊，没到一年就警告，太严格了吧。那父母绿卡究竟在国内可以待多久
请问警告的定义是什么？是海关说下次再这样就没收绿卡吗？
我在中国呆超过4个月，回美国过海关的时候都会被批注，算是precautionary。 ---发自Huaren 官方 iOS APP
那这次回来海关真的对我网开一面了，我也超过四个月了，他倒是问了很多问题，说为什么待这么久，我如实回答了，然后他就让我过了
我妈被带到小黑屋，后来有个说中文的老华裔过来跟她谈话。先是问她为什么在国内呆那么久，然后教育她：拿了绿卡就要把美国当自己的永久居住地，不要在中国呆那么久，经常这么搞的话说不定哪天绿卡就被取消了。最后还叹口气说：现在川普当政，移民越来越严，政策经常变化，你拿到了绿卡要好好珍惜，不要把它给作没了。

那请问是不是超过一年，申请I131就可以了？谢谢
没拿绿卡的时候问怎么才能在美国待久点，拿了绿卡问怎么才能在中国待久点，不管在哪里怎么都这么纠结呢？
从来就没有具体时间限制，理论上讲待一天都可以给吊销，只要海关官员有理由认为你没有把美国作为你primary居住地的意愿。
纯属误导！大多数情况如果拒绝签字，就送移民法庭。
yes, if need to stay more than 1 year, apply re-entry permit.

底特律，我爸妈来从来没问过问题，以前我妈隔了不到半年过来，人家也没问，每次还都是呆了半年。不过他们遇到过别人有问题。。。
