As we know, there are two options there could be:
The only problem with Option #2 above is that it will ALWAYS NECESSITATE an Audit. While this may not be a bad thing, as the two LCs need to be matched up, it may mean a long time before the case can even be adjudicated. This is primarily the reason why most of the people who have converted their BEC cases to PERM have not seen anything yet, while others filing a fresh PERM case have seen their cases cleared.
I am myself contemplating my decision on #1 or #2. My lawyer will not advise on what's best, and says that I should make a decision myself. Hopefully the discussion here will help me, and several others like me, in making the correct choice.
