What are the benefits of transferring from brokerage accounts where we hold ESOPs/RSUs?

Here are a few reasons why investing ESOP/RSU proceeds abroad is beneficial:
  1. Diversify your wealth: As the underlying value of the ESOP grows, more and more of your wealth might end up concentrated in the stock of just one company. In order to create a more robust portfolio, it would be prudent to diversify your holdings into multiple companies or ETFs
  2. Invest in the US market without forex fees and TCS: If you own ESOPs in US-listed companies, you can easily transfer USD from your ESOP account to a Vested brokerage account to invest in 5,000+ US stocks and ETFs. You would not need to pay any forex conversion fees or have funds blocked because of Tax Collection at Source (TCS) since you would not be transferring funds from India or converting currencies. 
  3. Fast fund transfers: You can move funds into your US brokerage account quickly via domestic ACH or wire transfers via a completely online process
