刚收到district office的信：
DearSir/Madam:
This is to notify that your Application for Lawful Permanent Residence has been approved. This means that you are now a lawful permanent resident of the United States.
In order to issue an alien registration card, you must be processed on Form I-89 within 15 days, at this office or none of the other offices listed on the attached sheet (if applicable). Your passport will be stamped with temporary evidence of your status when you are processed. Please make an appointment to come to this office for I-89 processing through our INFOPASS appointment system. INFOPASS can be accessed on the Internet by goint to www.infopass.uscis.gov.
这是不是说我的绿卡批了？ I-89是啥啊？ 问题是我的排期还差1年半，怎么会批呢？
谢谢大家的帮助。
