«Получающим российские паспорта предлагают давать клятву стране»

Here is my translation: Those Receiving Russian Passports are suggested to offer an oath to the country.

But what's really confusing me is this: Who is the subject of this sentence? I can see that the participle "Receiving" is in the dative, but past that, I'm really confused. It seems very ambiguous to me.

I'd like a native Russian translation to this sentence.
