It was a long time ago,1988,but was surprised how easy it was to enter the US here,they didn’t check my passport or stop any of the Mexican workers.As I needed a stamp on my passport I went to the customs post,a hut and had a strange conversation.Although I have a British passport the officer kept speaking to me in Spanish and I kept answering in English telling him I spoke English which he realised after about five minutes.He then noticed my visa was issued in Belfast which he asked me if it was near India.I thought that was pretty poor geography, really.
The people were friendly,most spoke Spanish which surprised me.
