Have US Visitor visa, apply for H4 later ?


	My fiance has a US visitor visa and has traveled to use once this year.

	We plan on getting married later this year

	I have a valid H1B visa (stamped) until 2015

	We plan on applying for her H4 later, when she arrives in the US using her visitor visa.

	Is it acceptable to apply for h4 after travelling on
	visitor visa ? Are there any possible future implications
	of doing this ?

           Please advise.


Why does she want to travel on visitor visa and file COS inside US? Why not apply for H-4 visa and enter on that?
