以后有问题,希望能向您多多请教 英文怎么说给美国教授写信,最后一句“以后有问题,希望能向您多多请教”不知道该怎么翻译

I wish ask for advice to you if I have any question hereafter.

if I have any question，I hope you can give some advice later.

hope I am allowed to consult you in the future if I have any problem
这样比较客气

Later, the hope can have problems to ask you
