Immigration Issues/parents just want to visit
my husband is citizen and I am PR and currently a student as well.
My parents just want to get a short visiting visa from Chine. they are chinese. my sisters are all overseas,
they don;t work anymore.
would it be hard for them to get a short visiting visa?
Yes it will be hard. The Embassies in China are not easy. They will think that they want to come and stay forever and be petitioned by you when you become a citizen to get green cards. They will need to show proof of ties to China like property, money etc. The decision to grant or deny a nonimmigrant visa is totally discretionary and sometimes arbitrary.
