Whether this guy is a good guy or not, your first priority is to get your family on board with taking actions to find you a suitable match. Your family needs to be your biggest advocate so work on them.
Only you know the family dynamics and everyone's priorities and motivations. It's natural that your Mom wants the eldest married first but she doesn't see how her strategy could back fire on her. Who does your Mom respect and have her ear? What about your dad? What does he want?
Wonder if this guy would run away if he found out that your parents would throughly investigate him. Yeah this happens in the States if people are dealing with Strangers. You don't have to hire one but casually say ' Would you rather provide your credit report, green card, and w 2 to my dad or do you prefer the private investigator' s copy? See if he runs away fast!
