Every phd student of Terence Tao is probably welcome at the Max Planck Institute For Mathematics: https://www.mpim-bonn.mpg.de/application Usually you need 2 letters of recommendation, I’d strongly assume that in the case of Tao one is enough. Generally please consider the new „ Max Planck Transatlantic Program“: https://www.mpg.de/25034916/max-planck-transatlantic-program
