Application form 'City'

It's probably in reference to the city where you reside.

I read articles.They said that Singapore was a city and a country.

Doesn't "Singapore" refer to both a country and a city?

The forms are probably designed by unimaginative people who live in countries where there are a number of cities. I live in a country which has cities, towns, villages, and hamlets, so I can see the potential for irritation and confusion.

I always see [a] the word, 'city' on [an] applications and I am uncertain what to fill in [the blank].
