It's a good personal statement, you sound very dedicated and your writing flows easily. English is not really my first language either but here's some little re-sequencing for you to consider:
I still have many problems and conflicts even though I have been living in the United States for three years.There are many hardships if you are not familiar with that country you live in .
I'VE BEEN LUCKY TO HAVE Having relationships with great and helpful people has been lucky . I especially appreciate my parentS, and am most thankful to themThey are AS valuable advisors, because They always HAVE respect FOR my opinion and future, SUPPORTING supported me to study aboard so I can TO see the world with open eyes.
I certainly can believe they are WILL always BE my supporters in my entire life.
Since my homeland is not a multicultural countr y, it is rare to have ANY relationship with foreigners.
From that time on, my future was planned, and I was sure that I wanted to be a part of a vibrant community IN THE FUTURE.
