Handbook of international migration

If you just bring the same book, even if it is pirated and used by yourself, it is ok. But if there is more than one copy of the same, then you are suspected of selling pirated copies, which is not allowed. It's better for you to send it by water, because air parcels are too expensive. In addition, if you want to send an air parcel, it is best to send a parcel below 10KG.

Even if it is expensive, it is better to buy books in America. Not worth it.
