130表格里面有个问题，如下，请问是怎么填写？看到有邮寄PO BOX地址，是写那个信箱的CITY,STATE? 谢谢

You should only answer this question if the beneficiary is in the United States and will apply for adjustment of status at a USCIS office in the United States.

If the beneficiary will apply for adjustment of status to lawful permanent resident inside the United States, you must provide the location of the USCIS office where the beneficiary will apply for an immigrant visa.
