本人今年h1-b 9月17日到期,新的h1-b申请刚批准(9月18日生效),我目前的签证也是9月17日到期。想在签证到期之前回国一趟(不想去签证了),8月28日回美。我能用旧的I-797回美吗?
-Yes.
离开机场时,应当交旧的I-94还是新批下来的I-94?
-You had better use the new H1 approval notice so that you can get the I-94 to match it. Explain to the IO that this new H1 is got by H1 extension if necessary (they should have your record in their system) so that the IO can issue a new I-94 to match the new H1 duration.
如果是交新的I-94,我是不是必须得去签证?
-No. The old visa will work as long as you return to US before it expires.
如果要是交旧的I-94,那我回来时海关给发一张新的I-94,有效期又是到9月17日,而I-94号码和新申请的h1-b的I-94不一致,是不是回美后又要用新的I-94申请一个h1-b的I-797,这样才能保证9月17日以后的合法身份?
-Correct. So you need to use the new H1 approval notice to enter US with the old visa.
