H1B Extension needs: Please tell me how often you work from home?

新人第一帖。H1B Extension, 然后最近被RFE。今天律师和我说，需要提供以下：Please tell me how often you work from home—and whether there is a pattern.  USCIS wants us to explain where you will be and when.
我确实每周在家上班一天，那这个要诚实写吗？如果我写在家工作一天，移民局会不会认为我这个工作是可代替的? 会不会故意的陷阱？

谢谢大牛们给点建议哈。
