尊敬的8老师和各位老师，想问问帮父母填485表的事宜：
1）Can interpreter 和preparer be the same as me?
2）on page5 part3 address history: just want to confirm we should put in only parents' address in China (not my current US address)?
3) on page6 part3 employment history: in item 11, provide your employment history for the past 5 years, should we just put in as "retired"? On page7 part3, item 19, provide your most recent employment outside of the US, should we put in the information of the institute where my parents retired from?
4) on page8 part5: is your current spouse applying with you? As I'm filling out form for each of my parents, should I check "no"?
非常感谢大家的帮助！感谢在先！
