In fact the initial sentence should be "They visited us last year."
Then, on Marcio suggestion "Did they visit us... (visit- the verb doesn´t take the "ed" in the end here, because of the particle '"Did").
Are they visit last year?

No.
I agree to "PPAULO" about the initial sentence to be incorrect:

- They visit our last year. (Incorrect)
- They visited us last year.(correct)

Therefore, I believe the correct interrogative form would be: Did they visit us last year?

So we think alike, with (...) I meant the rest of the sentence was like you pointed out.
Indeed I expanded Marcio answer only because we could have English learners that might not have met the topic (or the information) of DID/DO not supressing the "ed" of verbs.
