Hello palz

I need expert advice
I just secure US admission to school in the united state for an undergraduate studies and I decided to to take my spouse along since the options is open for me to bring a spouse or a dependent along. I want to know the probability of getting a US student visa if I take her along or is it still possible to send her visa invitation to come to US and join me later if incase I decided not to process her in my student visa processing.
The reason am considering that is because I don't want to lose this golden offer and we are also considering getting married soon. My plan is to use the visa opportunity to japa and take her along immediately after marriage because honestly am tired of this country and I believe the best gifts I own my future kids is to be born in a better country.

I need honest advise
