rec letters
Hi, You can ask them to write one letter only from each (thats what I did for EB-1---EA, and EB-2---NIW). Where ever it needs to be mentioned that it is in support for your "such and such petion" you can make it generic ie REF: VISA PETTION FOR MR/DR XYZ ---OR REF: IMMIGRATION PETITION FOR XYZ etc. Copies are acceptable. Post your email add and I may be able to send you some info.
