When do we use to be sorry to and to be sorry for? Have a look at the following sentences, it´s really easy!

• To be sorry to + infinitive = to apologise for a present action

I´m sorry to interrupt but could you come with me for a second?

• To be sorry for + verb with -ing = to apologise for a past/earlier action

I´m sorry for lying to you, I won´t do it again

Does this help? We hope so!
