Dear Friend, If you want to pursue a career as Corporate Lawyer, you have to improve your English first both writing and communication. Otherwise ,it will be a stumbling block in your path of sucess.
Secondly, you have to find out what is the basic role of a Lawyer in a Corporate environment.If you do your home work in this direction, you can easily make effort to aquire the requisite skillset for the purpose.
In another post,respected Expert have advised you to do post graduation in law.While taking admission into the P.G. program, you have to choose suitable specialisation subjects like Company &indl. law,Cyber law, taxation etc. to name a few.
Thereafter,during the studies find out established law firms dealing in Corporate law for internship, so that you can develop an focussed approach to groom yourself as a Corporate Lawyer. Besides, try to pull in similar professionals having specialisation in handling both opinionating and litigation matters who can be associated to run a successful law firm in your desired arena of practice.
Wish you best of luck in your endeavour.
