Hi Tamanna,
Don't mind, but you have to improve your English communication skills first, as you are currently working as an HR Generalist, which is very important. An HR person must have a good command over speaking and written English, and this core area expects the same, as HR is the base of an organization.
Secondly, as you want to change your job, I would like to suggest that you not change your job at this moment. You have to wait for some more time and need to learn a lot, as you have just started your career as an HR Generalist, and one year of experience is not enough, my dear.
Also, this change will have a negative impact on your profile, and you will have to answer to recruiters or a new employer as to why you opted for this change. They will perceive that you are not intending to work for any organization for a long time.
With one year of experience, as you have mentioned that you are currently earning 8K per month, you can ask for 10-12K if you have a strong knowledge and skills in your area of function and are very efficient with your work. If you have strong analytical skills, you can negotiate for 10-12K but have to demonstrate the same first.
Best of luck.
