I got my PR on 09/25/2003. I applied for N-400 yesterday based on 5 years of PR. I have only been out of country once since 09/25/2003 for 15 days. Just that one visit. If I am correct, I can apply any day after 06/25/2008 (90 days previous to the 5 year anniversary). Am I correct in this assumption? If I am wrong, I need to put a stop check order... Any replies will be much appreciated. Thanks.
