The literature states 1000-2000 is safe for basically anyone, but you really shouldn't be taking more than that without actually going to a doctor and getting your deficiency confirmed. Just because you have darker skin, it doesn't mean taking a higher oral dose won't cause other issues. IIRC daily doses above 2000 over a longer timespan can (infrequently) cause your vitamin B12 levels to fall off, and/or the amount of calcium in your blood to build up, so your doctor might want to schedule a follow-up appointment after some time has passed to make sure those levels still look okay, and adjust supplements for those variables accordingly.
