The modern world is providing opportunity for every capable person from all around. Immigration from one country to another has become a trend to discover opportunity. While people move from one place to another, they carry themselves with their own language, culture and their ancestral way of life. In the foreign country, they have to mix with the people quite different background who have different language and culture from their own. Hence there is always a collision of culture for such immigrants. Learning new culture becomes essential to sustain in alien environment while preserving own culture becomes their need for self identity.
The first thing that any immigrants should do is to learn the basic culture of foreign land. Otherwise they will be left behind and they will have difficulties in adjusting with new community. Learning how the people speak, how they greet each other, how they live their life, how and when festivals are celebrated etc will help to get mixed with the new community. Similarly, knowing how people work and how relationship work in new country helps to sustain and maintain livelihood. But learning new culture doesn't mean forgetting own roots.
Preserving the culture from where they come becomes is necessary for identity. Celebrating festivals and maintaining culture from the previous country not only helps to socialize with people of same country but also gives opportunity to learn their culture to new people.
Therefore, in conclusion we can say that, immigrants should not only learn the foreign culture but also spread their own culture for maintaining their social and economic life.
