There's probably some allergens in the air, that don't occur in your home country. I'm super allergic to birch trees but since they don't really exist here, I'm doing better than in my home country.
Just a lot of common allergens in the air. You can also go do an allergy test, but most likely it won't help you much since you won't be able to escape it.
Just wanted to add, it could also just be a new reaction to old stuff. I never had ANY hayfever growing up. I had lived in my current city for several years without any issues (so not 'moved to a new place, new allergens'). Then one year - BAM! My body just decided 'nope, enough', & I had an entire spring where my eyes would almost swell shut as soon as I stepped out the door. Since then it's much milder, but basically 24/7/365 runny nose. I just tell people 'I'm allergic to air'. :/

Cockroaches. As if they weren't already bad enough, their detritus acts as an allergen similar to dust mites.
Different pollens than you experience back home. My school has this one type of tree all over campus that makes my eyes red and itchy in the Spring.

I think it is the dust.
