谢谢您！86211！！！过去的两次三年的签证都是在多伦多签的

看来我最好是在绿卡拿到前不要再出境了，甚至加拿大也最好不去，否则恐怕每次入境时都要有麻烦，轻则要费很多口舌，重的话也许就把我的H1B给吊销了啊。。。我有没有可能再在什么地方三个月后再签到三年余下的时间的签证呢？再次感谢您！863211！！！！

The H1 Visa valitity druation for a Chinese citizen is normally for 3 months with 2 entries and that means you have to enter U.S. within 3 months for 2 times (normally you only need to enter US one time). it has nothing to do with your H1 duration within U.S. The Duration of your H1 status is decided by the CBP officer at the port of entry when you enter U.S. The officer will offer your H1 duration based on your H1 approval notice and indicate it on your I-94. So, you need to check your I-94 to see whether the I-94 duration matches your H1 approval notice duration (e.g. 3 years). If no, ask teh officer to fix it at the port of entry.
