@please_help , given your current long-term plans ( and unless something changes/evolves ), I would generally agree with you that you may not need an ITIN for her. However, if her plan is to become a US citizen ( directly through marriage or via being a GreenCard for five years ), she would be eligible for SSN. Personally ( and I recognize I am not in your shoes) I would make decisions on these tax matters based on longer term goals.
My best wishes for a very Happy Married Life ( I had 55 years with my wife till she passed due to incurable lung cancer ).
Is there more I can do for you ?
