請教各位老師： 在國外申請的移民簽證，持移民簽證入境美國，尚未收到綠卡的情況下，工作需要回國，是否可以出境回國？移民簽證是2022 年三月頒發的，護照上寫的是2022 年6月前有效。
-When you entered US using the immigrant visa, the immigrant officer at the port of entry put a stamp (endorsed the visa) on the visa in your passport. This endorsed immigant visa stamp is equal to the temporary green card which is valid for one year from the date you entered US. You can use this endorsed visa stamp to travel to China before you get the plastic green card.
