H1B簽證Visa的一些信息不太明白，請教過來人！
今天拿到了簽證，H1B,可是有幾個東西不明白，特請教過來人：

1、Visa type/class 是R H1B，R是什麽意思呢？

regular visitor

2、Entries選項是什麽意思，我的下麵是個數字“2”，代表什麽意思？是否代表可以2次入境？

right. 2 entries in 3 months.

3、Expiration date 是不是指入境的截至日期呢？ 這個選項的後麵還有4位數子，我的是1000，是什麽意思呢？
Yes. Entry expiration date, not your H1B expiration date. Don't know what's 1000. I also had same number.seems not specific on individuals.

4、還有一些信息


PED-×××××××××（是日期），這個日期又是什麽意思啊？

This is your H1B expiration date, same as your I-94 expiration date. You have to extend or leave US prior to this date. This date determines how long you can stay in US. Very important! Keep this in mind.
