My wife has a passport of country A + B1/B2 visa to US (country A citizens need a visa to enter US). I have a passport of country A and also a passport of country B + ESTA (country B citizens don't need a visa to enter the US, only ESTA) Since I didn't apply for a visa with my country A passport, I will use my country B passport to enter the US.
My question is:
My wife & I are planning to travel to the US and since we are family should go to the passport control together when entering the US. I have a concern that the security officer at border control will challenge us about why we are using passports from different nations and especially why I didn't apply for a visa for my passport from country A. Is this concern justified, or should we not face any problems?
