Angelique,
A person who applies for EA on the basis of being an applicant for adjustment of status gets EA and an EAD valid for 1 year. But a K-visa person who applies for EA on the basis of their K status recieves an EAD that is valid for the duration of their status. Useless for a K1, but great for a K3.
A visa's period of validity is not the same thing as the visa holder's period of allowed stay (period of status) in the USA. The visa designation and the status designation may use the same term, but a visa and status are not the same thing.

Dear VJers,
Could anyone let me know if there are any specific advantages for a K3 to apply EAD prior to applying AOS, instead of applying both at the same time?
I've also heard that a K3's EAD would be valid as long as the K3's visa expiration date. Is that true?
Thanks so much for all the great help.
