Import troubles? - Why no AVLP scenes by flown girls?

Fans and users so often call for import to Prague.
And actually more and more girls are actually flown over, especially from Brazil and Colombia.
But I just realized some of them do very little scenes or even none or fisting only.
Reason at hand could be STD detected at re-testing in Predvig lab.
This would be very very unfortunate!
Because its lots and lots of $$$ invested into airfare and sometimes also visas and logging in Prague. Giorgio Grandi stressed many times here that they re-test the girls upon arrival before they go to work on set. They do it even for girls arriving from Budapest because their labs are not reliable. Its a due precaution!
