I started my Windsor - Detroit daily commute on H1B for almost a month now and so far I haven't have any issue (knock on wood :-) ). Only thing is it is hard to estimate how long it will take at the border. Sometimes there are only few cars infront of you and can get through under 10 mins or couple times it took me almost 45 mins waiting to get my turn.
Hi Khayu - How is your commute going. Are you using NEXUS card. As you are the one who is commuting daily you are the best source for us. Can you let us know what kind of questions and problems we can have crossing both borders. Thanks.
