You can not practice as a Medical practitioner as Ayurveda is not accepted here.
But it is included in the Complimentary and Alternative System of Medicine( CAM
). So you can run Ayurveda Wellness Centres, which are licensed for doing
Massage and Bodywork.
You can practice Ayurveda treatments there, but invasive therapies in Panchakarma are
not allowed in the USA.
I would suggest you look for alternatives to practice medicine in the USA or stay in India
to practise as an Ayurvedic practitioner.
in India, there is a broad scope for you after completing BAMS
The areas which are available for a BAMS graduate to build a career successfully are:

 Clinical practice- In India, there are various traditions of Ayurvedic practice
like Panchbhautik Chikitsa, Nadi Pariksha, Dhatu Chikitsa, etc. Students can
learn such rules and follow them in their practice.
 Academics-Students, who cannot get the opportunity for MD, can go for post-
graduate diplomas available in various subjects such as Panchakarma, Balaroga,
etc.
 Research-Apart from MD and PhD courses, there are other good courses useful
for a career in research, such as MSc or PG Diploma in Clinical Research.
 Management and administration-MPH (Masters in Public Health), MHA (Masters
in Health Administration) and MBA (Hospital and Healthcare management) are in
great demand.
 Drug manufacturing-production of Ayurvedic medicines and other allied aspects
such as the cultivation of medicinal plants, trading raw materials in powder,
extracts, oils, etc.
Medical transcription, medical tourism, medical event management, medical journalism,
medical photography and documentation are also fields with a bright future.
