Europractice serves only European countries plus some culturally related territories, like ex-Euro colonies or ex-USSR. PlanetCrypto is based in US, so you will only qualify for MOSIS.
That is definitely not true. I have a chip I designed and fabbed through Europractice sitting in front of me right now and neither I nor my company have any connection to Europe.
For a while TSMC would not let them quote US customers, but that restriction was for that one fab only and it has since been removed. The only thing Europe-only is the academic discounts.
Europractice's IMEC team in Belgium (the ones who do UMC+TSMC tapeouts, but not GF) are absolutely top-notch, outstanding people.
