Hi,
I would be movingto the US via Pearson under H1B along with my wife and 2.5 year old son. I was wondering how long does the preclearnace at the airpot would take? And what are the documents that I need to carry with me - other than passport and H1B approved notice (I797?)
Do I just go the immigration like most people or I have to go somewhere to do some paper work first?
Thanks in advance.
