US Citizen looking for London Experience (IB,PWM, Corp Finance)

Bonjour! I am currently an indian born US Citizen looking to gain experience in the financial sector of London. I go to a small private school in New York and I'm currently in my last year doing an internship at a Goldman Sachs Co. My grade point average currently stands around 3.77/4.0, and hopefully will be 3.8+/4.0 after this semester. I am pursuing a Bachelor of Science in Economics and take much interest in what goes in the papers, journals, and economy everyday.

I would like to get my foot in the door at a financial firm in London, however, have a hard time finding forward guidance. I currently work in Private Wealth Management and enjoy the field and I am looking to gain experience in IB (however, I am open to any field in London).I tried searching here but could not find anything, please help - thanks!
