I got a green card in the United States and want to leave for a period of time to return to China, so what should I pay attention to before leaving the United States?

How should American immigrants maintain their green cards? Industry experts said that for American green card holders, it is best to make some necessary preparations when leaving the United States. Otherwise, after leaving for more than 6 months, the US Immigration Service may wonder whether the green card holder intends to give up the right of abode. So how do people who immigrate to the United States with green cards prepare before leaving the United States? According to experience, the US Immigration Bureau will doubt whether the green card holder has really given up the right of abode for those who have returned to the United States after leaving the country for more than six months, which is mostly the subjective judgment of the immigration officials themselves. Immigration officers will judge the situation of American green card holders from the following points: 1, family status: whether any family members or relatives have settled in the United States. 2. Work status: Do you have any career development, pay taxes, or apply for tax exemption for foreign income in the United States? 3. Economic and living conditions: Do you have real estate or long-term leased houses, bank deposits, credit cards, membership cards, automobiles, various insurances and certificates in the United States, and do you have tax returns? 4. Time, purpose and motivation of leaving the country: Is there a re-entry permit after leaving the country for more than half a year? Is there any evidence to prove the special reason for this long-term departure? For example, getting sick, taking care of sick relatives and dealing with real estate. Knowing the above situation, immigrants with American green cards should make relevant preparations for entry before leaving the United States. And put all the evidence that can prove that I have no intention of giving up my resident status in a convenient place and carry it with me to the immigration officer. Of course, if the green card holder applies for a re-entry permit before leaving the United States, then the green card holder will stay outside the United States for one or two years, but not more than two years, otherwise the US Immigration Service will give up his status as a green card holder.
