鉴于Relink的不确定性，在这里重申我并非鼓励Relink，而是提供一个参考的途径。
我在递交Relink Request前，曾在网上看到过下面这个Relink Request的Checklist，
列出来供参考:
1. A cover letter explaining what you want to do;
2. Copy of approval notice of the I-140 to link to;
3. Copy of I485 receipt notice;
4. Company offer letter (if your I-140 to link to is a company-sponsored)
5. Payroll record in 2004 and 2005 (just a print-out of all the salary
earnings)
6. A copy of the Michael Pearson Memo.
个人以为，The checklist of materials to sent for relink is dependent
