Hello every body

It's my first post....
I have a question.....my score is 467... I'm applying as married but my wife will not come with me,,as she is working on her phd.
My question is....Shall I accept the nearest ITA ( this month I hope

) and after landing I apply for her to join me???
Or it's better to apply together( which will reduce my points significantly )
Please guide me....and thanks in advance
