As an instructor, I would not send a student on an early solo flight with more than an 8 kt crosswind component. However, after the student has mastered the basics of landing they need to learn to handle the max x-wind for the aircraft. Here in Aus, we have a test of basic handiling (GFPT) and the student must demonstrate crosswind circuits.
Just a few weeks ago had to go-around because preceeding a/c landed on the grass after drifting off a 30 metre wide rwy in a x-wind. Another time, did a check flight with a student (records said he had finished all the sequences and just waiting for cash to do ppl test) 17-20 kt of x/w, absolutelu no correction at all! Different instructors teach different techniques so I thought he's just learnt to kick it aorund a bit later thats all. 200 ft, nothing, 100 ft, nothing, 50 ft nothing, starting to flare nothing, starting to drift over the grass and at quite an angle the rwy, TakingOverWhatWereYouDoing???? I landed it and as we were taxiing back in queried what technique he had been tought. Very blase said that what had happened "wasn't that dangerous was it?" Also revealed that he had run off said 30 m wide rwy when solo earlier in his training.
My point is that it is better to be safe than sorry. Ask your instructor for some dual in a decent x-wind. You won't learn unless you practice it but in those conditions you need to be competent at handling it before you get out there by yourself.
Good luck with your training and have fun.
