I crossed border last Tuesday,at first I
gave him my citizenship card, in a minte,
he asked for passport, so I gave
him my passport with my question "Do I
need passport for ground travel?" No
answer for this question in the end.
My understand, you'd better prepared
to aviod any complication.
For me, next time I travel, just give him my passport. It is easy and simple.
