Is "comes into being" used correctly in this sentence?

Question

--------------------
Before OSS *comes into being*, the licensing was carried out in each office so that the businessmen had to visit each office. After OSS *comes into being*, the licensing is processed in just one office. Until now, the project has given TA to some 22 OSS in 22 municipalities and regencies.

Answer 1

The first usage is not correct, because the verb comes does not match the verb was. Try came. I am not sure what 'comes into being' is supposed to mean, but I doubt that it is an optimal choice of words. The word 'so' is also somewhat odd. Consider:

Before OSS came into being, the licensing was carried out in each office, such that the businessmen had to visit each office. Since OSS came into being, the licensing has been processed in just one office.

Answer 2

in the first mention .. more correctly it should be 'eventuates' or 'eventuated' - depends on whether it's present or past tense

second time .. acceptable

the whole phrase sounds like official 'speakese'

Answer 3

I suppose.
