Immigration hesitancy

I'm confused. On May 1 Bertie Ahern criticized other EU members for "failing to throw open their borders to workers from new member states". But, when it comes the potential new new states of Bulgaria and Romania it seems that Ireland will say 'not yet' to those who might want to work here. There are now over 200,000 immigrants from the new EU members here and I suspect that the Taoiseach is hearing some grumbling.
