-wWe have had to improve our skills.

Please tell me if this sentence is grammatically right in the Present Perfect Tense or not. It's possible.

* Forming the Present Perfect Tense : sub + has or have + the past participle + O
The subject is not part of the present perfect. If the verb is intransitive, there will be no object - Our guests have arrived.

* "had to" is the past participle of "must".

'Must' has no past participle or tenses. 'Had to' is the past participle of HAVE TO, a verb we can use as an alternative to 'must' when we need to show tense.
