入境护照盖章处第一下边写上out 5 month
-That means you stayed outside US 5 months, nothing serious and worried about.
以前的红章下边都只有ADC没有写out多久。
-If you stay outside US for very short time e.g. 1 or 2 months, they may just note ARC and nothing about the amount of time.
Anyway, you will be fine unless you are absent in US for more than 6 months very often.
