As of December 1, Ira and Sandy will have been going together for three years.
If you mean last December, then it should read "As of December 1, Ira and Sandy have been going together for three years."
If you mean the next time we get to December 1 (in the future), then the verb tense is correct as is.

Either the interviewer or the committee, usually begins by asking simple questions about your background.
Neither the immigration officials nor have wildlife conservationist been able to find a solution that will protect both the U.S. border and these endangered wildcats.
The verb in this sentence is correct (begins) because "committee" is singular. However, there should not be any commas in the sentence.

Neither the immigration officials nor wildlife conservationists have been able to find a solution that will protect both the U.S. border and these endangered wildcats.
The phrases "immigration officials" and "wildlife conservationists" (<~~notice that it's plural!) are parallel; both have and adjective and a plural noun.

Typo!! Should be
...both have an adjective and a plural noun.
To get the answer to the question regarding the verb tense in the first sentence, you need to understand the context. If the sentence is referring to the past, then it should read "have been going." If the sentence is referring to the future, then the verb tense is correct as is.
For the second sentence, to determine if the verb is correct, you need to identify the subject. In this case, it is either the "interviewer" or the "committee." Since "committee" is singular, the verb "begins" is correct. However, there should not be any commas in the sentence.
For the third sentence, the verb tense needs to match the subject. In this case, the subjects are "immigration officials" and "wildlife conservationists," both of which are plural. Therefore, the correct verb tense is "have been able."
In the final sentence, there is a typo where "an" is missing before the word "adjective."
