Unless the weather is down forcing the ILS, you can usually expect the VOR/DME-A, cross CLIFO at 1500, then cross over midfield at 1500 to follow traffic on the left-hand circle to Rwy 19. Departures are normally off of Rwy 24, pay special attention to the altitudes and headings on the departure, Newark arrivals are only 1000 ft above your initial level off altitude.
Sometimes you have to wait hours to taxi, other times you can just hop in and taxi straight away. TEB had good days and bad days, though the bad days seem more plentiful has been my experience.
US Customs/TSA/Homeland security are turning the term American-hospitality into an oxymoron... Its all about the appearance of safety to the american public... I'm a dual UK-US citizen with FAA licenses, If I could find an N-reg job in the UK, I'd be there in a heartbeat...
Good luck at TEB.
