1）打印131 表格后手工填写吗？
-Fine. You can use your computer to type some items abd then, print it out. Some items cannot be typed using computer, so you may fill these items out using handwriting after printing the form out.
2）回美证两年期限是从他们离境日期算起？还是收到回执？还是拿到正式证件算起？
-From the date the I-131 is approved (i.e., from the Approval Notice issued date).
谢谢老师
