最近485 case被RFE了，主申请人是RFE 新的 i-693 和 documentary evidence to
establish that you continue to be engaged in your field. 副申请人是RFE 新的
i-693 和 employment history.
具体是这样的，1. Please submit a list describing your employment history
since you last lawful admission to the US on xxx, 2012. This list shall
include the name and location of each employer, the job title, and the dates
you held each position, The list should be supported by documentary
evidence which establishes your employment history.
evidence？ employment contract letters 可以吧？ 另外，LD 中间有几个月因为EAD
断了，所以没有工作。是不是还需要一个termination letter 来证明确实离职了？？
