thanks for ur opinion , i will think about it clearly n try to make a right decision !

Properly accessing the level of endangerment hinges on a correct understanding of the nature of your job and the place in which you will work and live. Maybe you could make two columns on a piece of paper, listing pros and cons and write down everything you can think of what constitutes benefits and disadvantages. You already mentioned in the pro column: good salary while on the cons column: endangerment. The first is a thing easily verifiable through a contract. The second, an assessment; therefore, you could try to find someone who worked the job you are offered and inquire into the nature of everyday life there, especially in terms of safety, to find out if it's really as dangerous there as you think, or if your uncertainty is merely an expression of the normal apprehensiveness towards all the new that everyone would encounter changing job and country. My best advice is for you to find people who have worked or work in your line of profession, and then build your decisions based on the knowledge and insights you gain from them.

" i " is always capital by itself , "u" is text talk (and I personally don't even text that way) and isn't formal ,you have to write I'm like this and so on like "Don't " also saying "I have no any meaning" is incorrect and is a really strange sentence, I really don't suggest using text talk / informal speck when you first begin learning english because that way of speaking isn't really correct and is sometimes accepted on the internet depending on who you're around , I hope this helps some .
