I noticed on the USCIS website there are two different addresses for each jurisdiction for sending in your N-400 package. One address is for "express/courier" mail, the other for first class mail (I'm assuming--they don't actually spell it out). I want to send my package USPS Priority Mail which will get there in 1-2 days on average. Not sure if this is considered "express" as USPS also has an express service which has guaranteed overnight delivery.
Has anyone else sent there package USPS Priority Mail and if so, to which of the two addresses?
Thanks. (Man, I'll be glad when that package is outta here!)
