My daughter, a US citizen, married a foreigner who entered the US on a student visa and subsequently received a green card, which has 18 months still to run before he can apply for citizenship. I have two questions:
1. Once the 18 month balance of waiting period has been reached in order to apply for citizenship, how long as a maximum period, from the date of application will he receive citizenship?
2. How long as a maximum period from date of application, will he receive citizenship if he applies now as a spouse of a US citizen? They have been married for three years.As the initial application predated their marriage, is he required to follow through with this same application, or are changes permitted?
