can indian nurse work as a travel nurse in USA?

I am not sure if you could do that from the start. you will have to go there get a license, work in some clininc and may be as an attachment you could do travel nursing,but normally i dont think it will be possible.

Only if you have the work visa to actually work in the USA. You will have to find a US company to sponsor you and apply for a work visa for you

Plus you will need to pass the licensing exams for foreign nurses, pass your TOEFL for English proficiency exams, and all other requirements
