BARDZO proszę o sprawdzenie-rozprawka!

Bardzo proszę o sprawdzenie rozprawki na temat: Wady i zalety wyjadu za granicę do pracy.
Working abroad is recently very popular, especially in poorer countries. For example, in Poland a lot of people are leaving for another countries, because they think, that there are better working conditions. In my opinion this idea has advanteges as well as disadvantages.
There is no denying, that working abroad has a number of advantages. Firstly, work abroad it is a good idea especially for these people who are learning English, because they can improve their speaking skills. What is more, they can also get to know something about foreign coulture and visit a lot of new places. Secondly, people who are go abroad have a hope that they will be earn more money than they have in own country. In majority of chances it is true.
Although working abroad, it does have some disadvantages. For instance, people who are going abroad and who can't speak English, they have a big problem, because they won't be able to speak with foreigners. Furthermore, they can't communicate with the locals and they can't asking somebody about any help. Another problem is security abroad. Tropicall diseases, political unrest or terrorist attacks are a few examples of situations that may spoil even the best stay abroad.
On balance, it seems that work abroad have as many disadvantages as positive aspects. The decision of whether to work abroad or stay in own country remains matter of personal choice.

Mam także pytanie: Czy w rozprawce można stosować skróty jak np.: can't czy muszę pisać can not??

Working abroad 'is' recently very popular, especially in poorer
countries. For example, in Poland 'a lot of' (lepiej many) people are leaving for 'another' (nie -OTHER) countries, because they think, that there are better working conditions (ale gdzie?tutaj brakuje slowa). In my opinion this idea has advantAges as well as disadvantages.
Firstly, workING abroad IS a good idea especially for thOSE people ..
..about foreign cULture and visit 'a lot of'? new places. Secondly, people who are 'go' (going) abroad have a hope that they will be 'earn'(EARMING) more money than they DO IN THEIR own country. In THE majority of 'chances' (chyba masz na mysli CASES) it is true.
'Although' (niewiem, czy uzylabym to slowo) working abroad, (bez 'it') does have some disadvantages.
For instance, people who 'are going' (GO) abroad and who can't speak English,
they CAN have 'a big'? (uzyj cos innego) problem, because they won't be able to speak with 'foreigners'(tzn z kim?)
Furthermore, they can't communicate with the locals and they can't 'asking' (ASK) somebody 'about any' (FOR ANY) help. Another problem is THE security
abroad.
'Tropical diseases, political unrest or terrorist attacks are a few examples of situations that may spoil even the best stay abroad' - (widac, ze to zdanie jest kopiowane z czegos innego).
On balance, it seems that workING abroad haS as many..
