Overseas can be an adverb or an adjective.
If you go overseas, you visit a foreign country which is separated from your own country by sea.
Overseas is used in front of a noun to describe things relating to countries across the sea from your own country. Overseas has a similar meaning to 'foreign', but is more formal. You use it especially when talking about trade, finance, and travel.
Be Careful!
Don't use 'overseas' after 'be' with this meaning. If you say that someone is overseas, you do not mean that they are foreign; you mean that they are visiting a foreign country.
