How much luggage can I take when I immigrate to the United States?

I don't think there should be any restrictions on this. The United States does not stipulate the limit of what you bring, only the airline's consignment limit. Generally, there are two large pieces of luggage, each of which does not exceed 23KG. This is an international uniform regulation. If it exceeds, just pay the freight. The money is not much, about 700 per box.
