"Aamir is at the shop."

Translation: आमिर दुकान पर है।

[AFAK847192]

Is it also correct to say "आमिर दुकान में है" ?

[maz1269]

में = in, 1st thing that came to my mind as well. but i don't know the answer to your question. could someone confirm that the difference between पर/में in this case would be like at/in in english?

Yes but although we say 'the shop' in English more commonly say 'the shops.'
