J1 豁免美方材料每一页都写CASE NUMBER?

除了补充文件，DS3035 package打印出来的文件要不要都写CASE NUMBER和Last Residence?（比如barcode page, DS3035, Supplementary Applicant information, Statement of Reason）尤其是有签字的那一页，我也要在页尾写这些信息么？非常感谢大家的帮助！

这是instructions：Check that the exchange visitor's case number and country/region of last residence is written on any documentation submitted, as well as on the outside envelope of ALL future correspondence with the Waiver Review office.

我在凡是没有case number的页面上都写了case number和residence
像ds3035上有的那几页，我就没有写
但是我也忘记在信封上写了。。感觉没写也没有特别大的影响
