H1B visa holder travelling to different city from what is mentioned in the LCA as work location. Will it cause any immigration issues?

Hi… I am H1B visa holder from India. My employer filed LCA with work location as Arizona but I want to go and settle in Boston. Can I enter the US from Boston instead of Arizona? Will it cause any immigration issues? My employer is flexible with the work location as he has end clients in both Arizona and Boston. My spouse will be travelling to Boston soon and I want to be at the same location to avoid moving later. Can you please help me understand my options here? Thank you.

Your employer will need to file H1B amendment before you start working from Boston.

Thank you and port of entry can be any city?
