Yes, but in this case, you would say "I can't get through".
Student or Learner
When someone is blocking your way, can we say "Excuse me, you blocking my way, i can't go through"
Was the "go through" is the meaning go pass that way?
I disagree. New Yorkers know how to deal with crowded conditions. It's the tourists, so busy gawking that they don't pay attention to their surroundings, who need a bit more encouragement. "Excuse me - this is my stop" is all that's required if the first "excuse me" doesn't work. Or "Pardon me, could I..." with a nod in the direction you need to go.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
