Eastbayer said:It usually takes two days to show up in the system and gets updated in the evening (my experience). If you sent it out last weekend, you may want to check again tomorrow. You can also go to the post office and ask them to check for you first. In my opinion, as long as the US Att. and local USCIS got your summon, you'd be fine. FBI never answers case status inquiries. Will it open the mail at all? Why waste the postage again?
If you are going to the court, ask them if you can file the certified mail receipts instead, as the proof. I remember Mohamedmohamed suggested similarly. Also check your local rules.
Well, it's been more than 2 weeks, all other mailings were delivered. I'll check with the clerk tomorrow - depends how anal the judge is about the procedure.
