I'm an Indian on H1B working for a US firm. I am going to London on a business trip end of this month and my American friend decided to join me. We made the plan after I got my visa, so I did not declare her as a traveling partner in my UK visa application form. She is a student and doesn't have a source of income but have some savings. I will take care of both of our expenses for the week we will be there. My questions are -
Should we approach the immigration together? I have an Indian passport and she just got her, which is blank because she doesn't need a visa.
How do I explain to the officer the reason for not including her in my visa application? She's not my spouse or girlfriend.
Should I carry my US bank statements to clarify I will take care of her expenses? Mine will be provided entirely by my employer, which is written on the letter of support I will be carrying.
