請教小白兔:我還需要做什麽嗎?

綠卡今天批了,移民局的email是這樣寫的:

we mailed you a notice that we had registered this customer's new permanent resident status. Please follow any instructions on the notice. Your new permanent resident card should be mailed within 60 days following this registration or after you complete any ADIT processing referred to in the welcome notice, whichever is later. If you move before you get your new card call customer service. You can also receive automatic e-mail updates as we process your case. Just follow the link below to register.

請問"complete any ADIT processing referred to in the welcome notice"是什麽意思?

另外,最後一句 "Just follow the link below to register." Email裏也沒有什麽Link. 是什麽意思?

謝謝你的幫助!
