“When will you come meet me?” was not accepted but is the same thing in English
I agree they mean the same thing, but I didn't ask if they do. They are different constructions and are, therefore, translated differently.
When will you come to meet me? - तुम मुझसे मिलने कब आओगे?
When will you come and meet me? - तुम मुझसे कब आके मिलोगे? (Several other word orders are possible)
