我係嚴明，我係埃及人，而家我喺廣州工作返工。

[In colloquial Cantonese, we don't use the word "工作" as a verb. We use "做嘢" or "返工" instead. 喺xxx返工 means "I work in xxx."]

我正在學緊粵語廣東話，

[In colloquial Cantonese, we use the word "廣東話" instead of the word "粵語", which appears in the written Chinese (lent as written Cantonese) text.]

因為我要學在喺香港讀書，

[I consider this sentence as a product of machine translation. I think your clause's meaning is "because I have to study in Hong Kong". Thus, I corrected it. The grammar pattern "verb + preposition + place name" in English corresponds with the grammar pattern "preposition + place name + verb" in Cantonese, e.g. 喺香港讀書. 喺 means in/on/at, 香港 means Hong Kong, when 讀書 means study.]

我也要交又想同嚟自香港的嘅人做朋友。我的嘅母語是係阿拉伯語話和，我長大在喺埃及長大。

[In Cantonese, we use the word "嘅" instead of "的". We also use the word "係" instead "是". "的" and "是" are both words from Written Chinese. In addition, for language's name in Cantonese, we don't use "語" (a word used in Written Chinese text), but "話".]

Besides that, the earlier modification of the essay is not correct. For example:

1. "我係xxx" and "我叫xxx" are both grammatically correct.

2. The sentence "係個埃及" is not correct - in both Cantonese and Chinese, we do not use the name of the country or region to refer the of the people in that country or region.

My mother tongue is Cantonese. I come from Hong Kong. Nice to meet you.

As a Hongkonger, our first impression to Indonesia is the origin of domestic helpers and Indomie.

Indonesia is a Muslim country with lots of cultural heritage.

It has been a Dutch colony, and gained independence in 1940s.

Its economy is booming, and it is a rising power in S.E. Asia. 

However, Indonesia was the base of terrorists and corruption.

The government in your motherland is surely doing something to tackle that problem.

I'm from Hong Kong, China.

I can speak Chinese (Mandarin, Cantonese).

我會中文，我會說普通話。我識講廣東話。

I'm interested in learning the languages of S.E. Asia,

especially Indonesian, Thai, Malay and Vietnamese.

I'm from Hong Kong, China.

If you are willing to, it's my pleasure.

I am from Hong Kong, China. I am watching the TV programmes from S.E. Asia countries (all are state-run TV programmes, in Malay, Vietnamese, Khmer, Thai and Indonesian), but I don't understand the meaning of most of their contents.
