I'm Doug, and I'm sorry to hear of the confusion. My goal is to provide you with excellent service today.
Your wife may only file a restrictive application for benefits---which allows her to take a spouse benefit now while allowing her own benefit to grow until age 70, if she is at least 66 at the time of her restricted benefit application.
As it stands right now, she will have to wait until she turns 66 to do this. Fortunately for her, even after the recent (2 weeks ago) change in social security laws, anyone born before January 2, 1954 may still make a restricted application for spouse benefits.
So, as soon as she turns 66, she can apply for her restricted spouse benefit and her own retirement will continue to increase by 8% per year until she reaches 70.
