Hi Hansini,
You can settle in Mauritius with a work and residence permit. All you have to do is to come to Mauritius on a tourist visa and do all your applications once here.
IT is an emerging sector here and labour competition is very less.
Being the incharge of an IT sector, i can say your husband do stand very good chances of being quickly hire and once the job in hand, then the work permit will follow quickly.
If you want more information, do drop me a mail on
bumal@live.com, i will guide you how to process.
Regards,
Bimal
