Location of U.S. port of entry for IR5 at U.S. preclearance

[EternalForeigner 57]

I’m helping my parents apply to sponsor my sister and their port of entry was the U.S. preclearance facility at a Canadian airport. But on the application it only shows US states, armed forces locations and unknown. Is it fine if I just left the state part empty and wrote Toronto Airport US peclearance in the city part?

You can just put unknown. It’ll be many years until she gets her visa and your sister may decide to enter elsewhere anyway.

It’s not about her possible port of entry though. It’s asking where my parents entered as IR5 visa holders for the first time.

Oh, apologies, I thought you meant where you sister plans to enter. 
 

In which case I don’t know I’m afraid, I’d put wherever your parents first entered the US as it only asks about admission, but may well have that wrong. 
 

Hopefully others in the know will chime in.
