I have received a job offer from a USA based company with a sponsorship license on one of its subsidiaries (A) in the UK. Unfortunately, i'm not sure if the role i have been offered falls under this subsidiary (A) or the 'parent company UK head office' (B).
Both of them are registered in the exact same address in the UK but have a slight difference in company name. Moreover, they have different directors when I looked them up on Companies House.
Is it possible for a company to have a license for a subsidiary but not the head office? Can I be sponsored through the subsidiary (A) if my payroll comes through them? Is it possible that these branches are grouped in a single license, such as on the 'Tier 2 Guide for Sponsors' Section 5? And if it isn't, will they have to add the head office as a branch or does that make no sense?
I am really hoping they don't withdraw my offer just because of this.

Thank you so much!!!
