How hard learning in a foreign country could be.

In an age considered the knowledge age, it's vitally important to attribute the significant flourishing of this age to that lantern which lights your way in a dark alley, it's education, as defined by Sheikh Zayed bin Sultan.
Since the first day Humans discovered how to teach and how to learn, education hasn't been easy, and will never be. Yet, when one wants to acquire a skill or expand their knowledge, studying with a teacher, or going to a school is no longer a necessity, but having grim determination is the most wanted trait.
As we begin the 21st century, going to a new country, whatever one's reasons are, becomes very possible. Immigration, refugee, studying abroad, and so many other things are all roads, that lead to being a stranger in an unknown world. Expatriates, therefore, will have to immerse themselves in this strange world. On the other hand, it could be a golden opportunity to enhance their learning as well as to dive into the vast sea of knowledge that awaits them.
Nevertheless, in such a foreign environment, learning becomes far more harder, and it costs a great deal of hard work and determination. Expatriate students could face difficulties other learners don't. They, for example, have first to master the language of the country they've moved to. Furthermore, learning in a different society is not like learning it in their their own, especially when race or/and religion are dissimilar, they might get insulted, hurt, fired or excluded.
One other reason is money, which is always a problem for everyone.
The expatriates mostly have to start from zero, having no job, relatives or family. Most of the times, they have nothing or even know nothing. Therefore, how could they pay for their education along with their family's, not to mention that in some countries, citizens cannot afford it.
So next time when you meet your expatriate classmate, try not to be mean or rude, and appreciate the fact that they have indeed worked extremely hard to get to this position.
