Hello there Pipergirl!
Well it looks like things are returning to normal over here and as previously stated the only restrictions are solo flight in Class B and over certain TFR sports events, etc. Best bet is to check the AOPA website as it is very comprehensive and should answer all of your queries. As with before immigration will be tight, so dont mention you are coming over to do flight training, just for a visit!
Good luck and happy flying....its still touching 30 degrees most days here and the humidity is dropping too, so ideal!
