回复：回复：恳请老猫和各位看看我的回复帖帮忙分析:

Chances are your sister will get a booking notification after the first court appearance.  Then she will need to go to local police station to do fingerprinting et al.  In such case, she still has arrest record. At least, it will appear this way if she does a FBI fingerprinting criminal record check later.

5)当时警察只开了传票,但没有送到警察局,所以没有按手印和照相.这种情况算ARREST吗? 会有 arrest record 吗？

沒有正式 areest 就不是 arrest.
