Also assuming that you're not working (and being paid by a US company) out there. Going out for meetings, inspections, etc is fine if you're still employed by a UK company (roughly).
no payments happening, visiting the FDNY for 3 days as work, remaining stay is pleasure. Likewise Mrs OWK will work remotely for those 3 days, then tourism for the rest. sounds fine then.
Should be OK (I'm actually sat in an office in NY at the moment) but immigration can be a bit dim so you have to make sure that they understand that you're just visiting for business rather than working properly.
I sometimes have to do a bit of explaining but it's normally fine.
very helpful thanks
