I have a good friend in USA who is a permanent resident and is married to a US citizen.
They have only one income (although his income is a bit over $100K per year) and his wife (who is the citizen) has not had any income for over a decade. She also does not have any debt. They have common budget and he had paid off the little bit of debt she had (less than $4K) last year.
His own debts are moderate (less than $10K total on revolving credit + two car loans totaling about $38K). Neither one of them has any bad credit markings on their credit report. They have been married for over 20+ years but moved back to USA about 4 years ago (they lived abroad because of his work and kept filing the international tax returns to IRS).
Anyway, he told me that her FICO score is about 50 points higher than his.
Could this be caused by that he is a permanent resident instead of a citizen?
