Is it written correctly?

Please, correct me If I have done something wrong, I have the next exercise:

Read this email from your cousin, Ana.

Hi,

I saw your mum yesterday. She told me you are learning English. That’s good news! But I want to know why you are studying English. Why is learning the English language important to you?

I wish you luck!

Ana

Write an email to Ana and answer her question.

My answer:

Hello Ana,

I am glad you remember me, it has been a while since we chatted last time. Well, It's true, I have been learning English for 2 months because I got Green Card so the last thing I have to do is to learn basic grammar, just to not get lost in the completely new country. Plus, maybe I will get a job during the first week, and if this happen, I would be overjoyed.

Thank you!
