Correct, if you vacation is under seven days then you don’t have to report it. I go away to NY to see family and friends all the time. I usually just go for the weekend. I leave thurs and come back on Sunday eve. My family takes Friday off so we can spend time together. They work M-F 9-5pm usually.
It important that they mean under 7 calendar days and not 7, 24 hour periods. So if I leave on Tuesday. I have to be back before the clock strikes midnight on Tuesday night/ Wednesday morning. Especially if you are crossing state lines.
