learning english

I am learning English because I want to work in foreign country countries like the USA, and Canada. I am Computer Eng. but I have lack of speaking English don't speak English well. 

Notes:This is a great start! The words/letters in blue are my corrections. 

1. I changed the word "country" to "countries" because you are refererring to more than one country, hence the plural form of the word. 

2. I just added "the" to referr to The USA as it is always referred to with a The.

3. Instead of using "," I replaced it with the word "and" because you are referring only to two countries. You can use "," if you are referring to three or more and then use the word "and" for the last noun that you will be using here's an example.

I want to work in The USA, Canada, England and The Philippines. 

4. I changed "B" to lowercase because you only capitalize words at the start of the sentence or with a proper noun.

5. I understand what you are saying how ever I replaced it with a gramatically acceptable group of words.
