...increasing blacks would flock into clean and untouched Latvia I love...
wang:
I don't think EU would treat Latvia kindly.Core nations in EU would only take care of their own benefits while at the same time they would only treat Latvia as a source of labor and sluts.
You must be right on that. Latvian government already obeys the EU parliament and directives. In many aspects it already treated that way.
As I know, some places are already prepared for refugees from Africa and Syria, for example.
It is inevitable that Latvia, sooner or later, will be flooded with foreigners, and they all won't be sort of "high quality", because having such large strategic territory for relatively small amount of people would mean impossibility to protect and handle it properly; so Latvians
will need slaves...
wang:
I am not sure whether I can get high-paid if I go for IT in Latvia.
Latvia is full of IT-related workers, but they are not paid well neither. Having no experience, you may possibly get the same 500 EUR/m, and that would be "black money", i.e. some of the official taxes wouldn't be paid. Getting 1000 EUR/m on hand would work only for relatively professional, unbeatable workers - and truly, that's a rare case...
wang:
I think if one person works in Latvia,the most terrible for him is to accumulate enough money to buy apartments.
This is true. Young people are all up to taking loans, and they are expensive in paying.
However I have mentioned most "great-valued" and fetish examples of properties. They are rarity, similarly like millionaires in Latvia are

Mostly, an average-cost apartment in the old-USSR-build house would cost you not more than 40,000 EUR, and that would be quite a possible place to live (but it wouldn't be completely new, refurbished and so on).
180,000 EUR is quite a great price to get something new and fresh, closely to the center of Riga or even Old Riga. But for this price and in this prices range, it won't come fully furnished and most likely you will need to get some extra things like flooring. Check the example below.
For you like a foreigner, it would be very preferable to buy something in "plug and play" style

You won't find a professional which could help you in this.
