N-400表上要求填写我最近5年的居住地址。
这5年我回过2次国内，一次呆了1个月（白交房租，继续租房东的房子），一次呆了5个半月（借老同学家趴车收信）。
这两次回国期间我的居住地址该写国内的地址还是美国这边的地址？
-Because your stay in China was not > 6 months continuously, you may not need to list the address in China there. But you need to report the dates you stayed in China in N-400 so that USCIS can check whether you meet the requirement of physical presence.
另外这5年我搬家比较频繁，表格上给的4个地址栏填不下，需要附加说明么？
-Fill the addresses in the same page of the another From N-400, and print it out and insert it to the N-400 which you will filed.
