In wife's absence from the country, will husband get his green card

[jennym]

The couple applied for the green card together. The husband applied under the EB1 category and his wife also applied with him as dependent. The green card of the couple has been approved and is expected to arrive in a month's time. The wife is not in US currently. She is outside US. Will the husband get his green card & the wife's green card in his wife's absence? Will there be any complications in the husband's green card in this case?

It is urgent. Please reply as soon as possible.
