Well good luck. But you can't work here without a work VISA and that process is complicated and likely nothing anyone in the cannabis industry is going to attempt and if so it would be denied because as I already stated cannabis is illegal under Federal law here. You can't just come here and work. You can visit as a tourist but if you get caught working without proper paperwork you'll be deported and could end up sitting in an ICE facility for awhile. But you will never be granted a worker VISA to work in the cannabis industry until cannabis is no longer illegal under Federal law. I hate to be the bearer of bad news but your dream will never happen until the law changes. So best to move on to your next career option for now.
"Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for temporary stay, or an immigrant visa for permanent residence. Temporary worker visas are for persons who want to enter the United States for employment lasting a fixed period of time, and are not considered permanent or indefinite. Each of these visas requires the prospective employer to first file a petition with U.S. Citizenship and Immigration Services (USCIS). An approved petition is required to apply for a work visa."

"Under federal law, employers are required to verify the identity and employment eligibility of all individuals they hire, and to document that information using the Employment Eligibility Verification Form I-9."
Labor exploitation is a humanitarian issue and poses risks to our nation's safety and security. Many industries exploiting workers are part of our daily lives — such as food and agriculture, manufacturing, clothing production, health and beauty services, childcare and cleaning services.
