Can anyone tell me that how can i become a pop singer in usa?

First you gotta move here and meet people who are also into music, then you can go on from there :) If you're as good as you say you are, maybe try out for some competitions to get your name out there. Its not an easy thing to do, you cant really just up and become a famous pop star, BUT dont let that get you down! You can certainly do it if you put your mind to it! I hope everything works out :D

Everyone has dreams. Want you want is not something you can gain over night. It will take time. Uploading videos on to YouTube will get you noticed (Lots of producers are now on YouTube searching for singers). Joining Selena Gomez's band would be close to impossible. She is not looking for another member. Search online for producers.

Hmmm let's see, dress half naked. Have a publicity stunt. Lip-sync. Go to rehab. Punch some one in the face......just kidding. Youtube is a great outlet for upcoming artist post a video every day. Make yourself look presentable. Fix your hair, maybe little lip gloss, make-up. Not too much you want to look natural. Just a thought. Most labels look for something different and typically want new talent boxed and ready to go. But always remember to be yourself! Good luck!
