Sheikh Abu Iyas Mahmoud bin Abdul Latif al-Uweida from Jordan answers this question, in relation to a question put to him about employing a foreign Christian live-in maid. He says,

ولهذه الخادمة النصرانية أن تصلي صلاتها في بيتك، لأن الإسلام لا يمنع غير المسلمين من أداء عباداتهم

“[It is permitted] for this Christian maid to pray her prayer in your house, because Islam does not prevent non-Muslims from performing their worship.”

In fact it is also permitted to allow Christians to worship in a mosque.

“The Prophet ﷺ wrote a letter to the Christians of Najrān, which began, “In the
Name of the God of Ibrāhīm, Isḥāq, and Yaʿqūb…” The Prophet ﷺ then invited
them to worship Allah and advised that accepting Islam was better for them,
but also gave the option of paying jizyah (tax). Should they refuse both options, the last resort was war. The people of Najrān convened to discuss their options. One of them said, “We know that there is a Prophet predicted from amongst the people of Ismāʿīl, perhaps it is him.” They eventually agreed, sending a large delegation of 60 people to Medina.

They arrived at The Prophet’s Mosque and were received by the Prophet ﷺ. It
was time for their own prayer so they asked permission to pray. The Companions hesitated to allow them to pray in the mosque, but the Prophet granted them permission. The Christians then turned towards the east and prayed their own prayers inside The Prophet’s Mosque.”
