The fact that AUSA is assigned and I hand delivered summons to US Attorney's office, the 60 day clock has already started, right?
Can I file Proof of Service without proof of delivery attached? May be I should with clerk as well?
When you hand deliver it to AUSA, they usually stamp and sign the second page of summons. Just fill the remaining info on the second page and file it with the court. You can file it separately, but it does not really matter as the clock starts from the date you hand delivered the complaint to USAtt Office.
