Consider timing 

The timing of your exchange can greatly affect the rate you receive. It's a good idea to exchange your currency during times of low volatility to get the best rate possible. 

Avoid exchanging at airports 

Airport exchange rates tend to be higher than other exchange locations. Try to exchange your currency at a bank or exchange office in the city. 

Shop around for the best rate 

Different exchange offices and banks may offer different rates, so it's worth shopping around to find the best deal. 

Consider exchange fees 

Some exchange offices and banks may charge additional fees for exchanging currency. Be sure to factor in these fees when comparing exchange rates. 

Use credit cards with no foreign transaction fees 

If you're traveling to India, consider using a credit card that doesn't charge foreign transaction fees. This can save you money on exchange fees. 

Don't exchange too much currency

Try not to exchange more money than you need, as you'll lose money when you exchange it back to USD. 

Consider using a travel card 

Travel cards can be a convenient and cost-effective way to access money while traveling. They can also help you avoid exchange fees and provide better exchange rates. 

Be aware of scams 

Be cautious of exchange offices or individuals offering exchange rates that seem too good to be true. Stick with reputable banks and exchange offices. 

Keep your receipts 

Keep all of your exchange receipts in case you need to prove your currency transactions later.
