What are the consequences of children applying for refugee cards in Israel?

There are no consequences. Returning to China with a refugee visa will not affect relatives and children at home. It has a great impact on yourself, because if you get a refugee visa, you may never return to these countries after returning home. Refugee visa means that if you are in trouble, you can only live in a foreign country and need foreign protection, but if you return to China voluntarily, it means that you don't need foreign protection, so once you return to China, it is difficult to go back. Refugee visas are best left abroad.
