TAF visibility and Appraoch WX minimum RVR

[yunje]

When dispatch long distance flight (more than 2hour / In DISP PHASE)

- TAF Forecast visibility : 600m
- AIRPORT appraoch minimum : CAT 1 / VIS 800m (or RVR 550m)

Is it possible to dispatch in this case? (with one alternate airport)

TAF is below AIRPORT VIS minimum but above RVR

if you can help me with this, I’ll really appreciate it.
Best Regards!

Does the airport have a CAT II approach?
