It is also very favorable for people studying abroad to apply for CCB's credit card, because my previous credit card was also CCB's, and it is ok to use it. In addition, CCB, ICBC and BOC also have offices abroad. It is easier for the landlord to find staff to handle any problems with his credit card abroad, and the landlord can try to apply. Generally speaking, after the parents handle the main card, the landlord can handle the secondary card. For specific application, the landlord can go to the forum of I love cards.
