Will I be able to check-in curbside for an international flight at MIA?

Sorry, I forgot to tell you I am flying AA.

Since you haven't gotten a response, I'll give you my general input. I'm not familiar with MIA, but most airlines/airports won't let you check-in curbside for international flights. The airline personnel (not the baggage handlers) have to verify your id, passport, visa etc before they'll check your bags.

The time I flew internationally out of Miami - was awhile ago - you could not do curbside for international flight. As dfr said, I've never seen an airport in the US that allowed that.... Not in years......

In May I flew out of MIA and had to go inside to check my bag. There was no curb-side check in for international travel.

We had the unhappy experience of going through MIA on AA in March - the sky caps charged $3. per bag plus tip and if you had your passport and itinerary they were checking in curbside for int'l flights. It took forever as he went inside.
