请教8老师: 在I140的排期变成当前之后，是不是必须在一段时间内来美国，否则就会从USCIS的记录中删除？
-No.
还是说有几年的保质期，这样我什么时候申请到了美国的一个满意的工作，就可以通过file I-864来申请immigrant visa?
-Yes. But the I-824 and the immigrant visa application process may take about one year. So, you have to have a plan in advance. If possible, you may ask the employer to file H-1 for you and then, you enter US and file I-485.
谢谢8老师！
