这种情况, 也是可能拿到签证的.我的经验如下(我的原件在公司寄给我的过程中丢了):

　　1. 要求公司律师把CERTIFIED COPY OF I797A 以及APPLICATION PACKAGE (包括I129,LABOR APPLICATION...)直接发传真给使馆.

　　2. 要求公司直接发传真给使馆解释丢失原因.

　　3. 面试交材料是一定要让收材料的人查传真, 并把传真和申请材料放到一起给VO.

　　我是08年1月在北京面试的, VO是亚裔LADY.她只问了几个简单问题, 没有要更多材料:

　　Q: You are applying for H1B visa?

　　A: Yes.

　　Q: What is your position?

　　A: I'm a Engineer.

　　Q: Where is the original I797A?

　　A: It was lost in the mail when my company sent it to me through Fedex, the [1;35m [m

　　fax package sent by my company lawyer include a certified copy of the I797A.

　　Q: Why did you come back?

　　A: Vist family for emergency.

　　千万别把I797原件丢了, 很麻烦. GOOD LUCK TO EVERYONE.
