You can write an email to Park requesting information but be warned you will be shocked once you deduct Portuguese taxes and factor in the increase in cost of living , both have been on the rise due to the financial crisis. VAT at 23% and 4-5000 Euro incomes being hammered in southern European countries , you can count on a mediocre living standard with little or no savings and questionable job security. In my opinion they are just fishing for bargains and If you're smart Asia is the logical step.
