Werner is right in what he said and ... he isn't !
It's simply so that as from July 2006 the new budget came together with several laws changed. Werner mentioned what was valid until July 2006 or may still be valid, as the administration needs time to carry out, what the government has decided. Until then the old laws are in force and nobody can predetermine exactly when a new law will become valid.
Some important changes are:
1. As a tourist its no longer possible to stay in Mauritius for longer than 3 months. This will have an impact especially on those who lived 6 months in Europe and 6 months in MRU. But these people can now live (not work!!!) 12 months a year in Mauritius if they can show that they spent around US$40000 a year in Mauritus. Guess this could lead to a new market place: Receipts exchange for expats
2. Shareholders of companies although not of Mauritian nationality can now get the permission to buy land if they fullfill some conditions (# of employees, revenues etc.) and it can be stated that its main use is for the company. This is something completly new in Mauritius !!! Before it was simply impossible for Non-Mauritians to own land in Mauritius.
3 Every Mauritian company can hire a non mauritian employee if they can ensure that he/she will earn more than 30000 Rupees/month.
I think since 2005 it's also possible to rent land for a period of time i.e. 20 years or so (Tamarin). After these years, somewhere was mentioned, that one should have the chance to extend for another 10 years or so. But at the end the land and everything on it falls back into Mauritian hands.
Hope I could clearify the situation a bit.
