Narrative:
We were descending on the MIP4 arrival into lga. We were cleared to the biley intersection at 13;000 feet and were then re-cleared to cross [beuty] intersection at 10;000 feet. On the descent to cross [beuty] intersection at 10;000 feet; ATC queried us if we would make the restriction. It was at this point that we realized we'd put [another airport] altimeter setting of 29.52 instead of lga's setting of 30.52 into our altimeter. We fixed it and made the 10;000 foot restriction. We are unsure if we missed the biley at 13;000 foot restriction; but the captain stated we were cleared to [the] intersection to cross at 10;000 feet before reaching biley at 13;000 feet. Otherwise we missed the biley at 13;000 foot restriction; but I'm not sure.we just missed the check in multiple spots. The approach checklist should have caught it but we saw the [old] altimeter setting that happened to be exactly 1;000 foot difference on altimeter.
