这是我的，希望能帮到你。
Dear Prof. Cater,
How is everything going? Hopefully everything goes well for you. Thank you
very much for your recommendation letter for Green Card in 2012. I am very
grateful for your help. And recently I am struggling with thinking that
whether should I contact you again. Because the priority date of National
Interest Waiver of China is at the beginning of 2009, I will have to wait
many years, most probably 3-4 years more, to get through this. So I am
considering to upgrade my petition of Green Card to EB1A category which is
Alien with Extraordinary Ability category. And this need a little bit
revision of previous recommendation letter. To save your time, I've done
that, and marked the revision red in the attachment. But could you please re
-sign the recommendation letter for me? I am feel very sorry to bother you
again about this issue, thank you very much for you kindly help.
All my Best Regards,
Fans
