For your kind information USA is a place for talent and oppertunity.
To get to heights you need to be clear, capable, commited, communicative,assretive ……
most important hard working and honest.
You got to respect others and be a team player.
Unfortunately many accept this but when it comes to prectice only certain people implement these. They are the trend setters and leaders and we need to follow them.
Accent is one aspect. What you are, what you can, what you communicate, and what you do matters more to get the results.
We all need the results.
Wish you all the best.
