I just got into TJ today. They are cracking down. There was no agent at the custom booth and I stood by myself. Someone saw me and took my passport and led me to a room where I was asked where I am going and why? I said essential services that are too expensive in USA. Was not asked about my suitcase and duration of stay. I was nervous that I flew all this way to get denied. Well I had a nice agent! He simply said go ahead and now I have 4 days here. My advice is to not go here until restrictions are over. I think I just got a nice agent this time.
