Texas - DFW immigration wait time (foreign)

Hello,
can anyone tell me about immigration wait time (foreign - non-US) at DFW around 2.30 PM ? Is 90 minutes from landing enough to catch a connection?
I am supposed to arrive with Lufthansa from Frankfurt, week before local Christmas.

I know this is an ongoing question, but approximation would be helpful.

Thank You, all best.
Alex

Hi ialeks,

If your bags are tagged to your final destination ( simply drop them off at the recheck desk after clearing customs) and you have your boarding pass for your connecting flight ( ie you do not have to check in again) then 90 mins should be ample ( esp if you are one of the first off the plane). Although DFW is a large the skytrain links all the terminals airside and only takes 10mins to get to the furthest away terminal.

Regards
