I am from Pakistan, and as a writer of Western stories, I find myself uncertain about the ideal setting and country to use. What is suggested?

The rule of fiction is to always write in your natural settings, places, and sceneries you can comfortably describe; that's how you create an allure that pulls in your readers.

Take them to the mountainous sceneries of Pakistani or the crowded streets of Karachi, and let them smell the sweet aromas wafting from Pakistani homes, as the distant red ball sets on the horizon.

Awaken and tantalize your reader’s consciousness with Pakistani street noises, then you can bring them to New York as foreigners who suffer from culture shock, and try to learn strange Western ways.
