Office politics

I recently started a new job 10 days ago. It's a UK-based company that offers remote work opportunities in India. All of our senior managers are foreigners, but I have an assistant manager, who is below the senior managers, and he oversees the team. He has asked me to learn Hindi within 2 months, as the rest of the teammates are from North India. However, when I discussed this with my teammates, they mentioned that he is very helpful in other aspects. Could you suggest what actions I should take? Should I report him to HR? I’m concerned about complaining, as he might target me in return.
