No. In this scenario the representative may draft and organise, but each eligibility answer should be verified by the applicant before submission. Gold Card decisions still turn on lawful permanent resident eligibility, admissibility and an available visa, so an unverified answer risks a request for evidence or a refusal.
Verifying answers with an applicant who is abroad
Build a short confirmation cycle into the travel plan: the representative sends the drafted answers, the applicant reads and confirms or corrects them in writing, and only then is the item treated as final. Where a fact is genuinely unknown — an old entry date, a name spelling on a prior application — investigate it against records rather than guessing. If a government notice appears to contradict what the applicant remembers, investigate the conflict instead of repeating either version.
The applicant must still be eligible for permanent residence under an EB-1 or EB-2 classification as determined by the authorities, admissible under the ordinary grounds, and able to obtain a visa number under the Visa Bulletin. Successful applicants then proceed under existing EB-1 or EB-2 classifications, subject to the eligibility, admissibility and visa availability those classifications carry.
