Spouse name on passport?

[indianium]

Hello,
Is it necessary for permanent resident/ US citizen to have spouse name on their passport before applying immigration papers for spouse?
Also, do spouse need to do same or either of one having their spouse name on passport is OK?
How it will affect immigration process if none of them have spouse name on their passport?

It is not necessary. The wife does not have to take the husband's lastname, but it may bring questions as to why not. It would be a stronger proof though, if she changes her lastname to her husbands (using the marriage certificate) as it shows stronger commitment.

why not ask him to change his name to hers?? or maybe hyphenate their names

there may be professional reasons for either of them to be sticking to their names.

Anyways this person is not talking about wife taking on husbands name but have spouse's nameson each other passports, which is not compulsory but a good idea and does not take much effort to put that in.
