Thanks for getting back to us, @Shamaz1ng. The steps shared by my peer, @GebelAlainaM should resolve this issue.
I'd recommend consulting your accountant to further assist you with proper accountng of your books after the 2 companies are being separated.
Once done, you can create a new company file for their EU business to account your Europe business income and expenses.
To get this done, you can choose your country you'd like to set-up through this link: https://quickbooks.intuit.com/choose-country/.
Let me know if you have additional concerns about your business. I'm always around to help.
