What if it is impossible to get to VMC? If we are talking about an IMC qualification I wouldn't be planning an approach into an airfield that we simply couldn't get into. A good 1000' cloud base will allow you quite comfortable in the event of rt failure to get visual and sort yourself out.
Even during IR training you wouldn't be planning an approach where you simply couldn't make it.
If the hold is near the approach, you still need to leave the hold but dont descend in the direction of the approach. Just get down below hold minimum as soon as poss.
