What options do I have to deposit money in my Debit Card?

There is no such thing as putting money in the card. Only in the connected account. And you will have to ask your bank what options there are.

You can do it online. Just to let you know you might have to do a currency exchange because some countries might not accept usd

Contact your bank and ask them how to deposit money into your account from the country you're in.

Your options are to put money into the account attached to the debt card........
