The round after Mexico is yet to be announced.
Now that Andretti + Danika Patrick are on board, I think a race in the U.S. would be a good idea. California, Florida or Texas, someplace with a good March weather.
Got to check if there is conflicts with IRL and Nascar..
P.S.
IRL starts in April, so we are clear there...
March 29 coincides with Nascar's Martinsville (Virginia) event (but anyway,Nascar races almost every week, impossible to avoid conflict)
May I dare say Laguna Seca?
