Too many posts to sort out the correct versus the incorrect, the relevant tangents versus the irrelevant tangents. I hit "like" above for most of those I explicitly concur in.
SUMMARY of KEY OBSERVATIONS AND CONSIDERATIONS:
The documents check interview is in fact an INTERVIEW and
personal presence is required. Applicant must attend. Applicant must
personally answer the questions asked.
No language requirement for applicants over 55. Again, applicant must personally answer the questions asked but can do so through an APPROPRIATE interpreter . . . sometimes a family member is OK but NOT always. If, for example, the family member is also applying for citizenship, it is likely they will
NOT be allowed to act as an interpreter or even otherwise accompany the applicant during the interview. Family member cannot answer for the applicant, even if the applicant is present, and if the family member appears to be answering for the applicant or otherwise helping the applicant answer questions, that too is a reason that family member might NOT be allowed to act as an interpreter or otherwise continue to accompany the applicant during the interview.
If the applicant cannot appear for the interview, it is best the applicant communicate with IRCC and ask to reschedule the interview. Unless the applicant has designated a personal representative,
ONLY the applicant can communicate with IRCC by telephone. To have someone else communicate with IRCC (which given the language situation, appears to be the only way the applicant can), that person MUST be a designated personal representative. If the form was not included in original application, it can be submitted at any time.
If the applicant fails to get the interview rescheduled, and fails to appear, the interview will likely be rescheduled ONE TIME but I am not certain of this for an applicant scheduled only for an interview . . . IRCC will automatically reschedule the test-interview event for those who fail to show the FIRST time, and I would expect (without being sure of it) the same for those to be interviewed without taking the test.
Nonetheless, communicating with IRCC is probably important . . . and for sure necessary if a second-scheduled interview is missed.
Note:
Inability to attend a scheduled event due to being abroad tends to invite suspicion. How much so depends on the particular details. If the applicant has been abroad so much in the last five years that he or she is
cutting-it-close relative to complying with the PR Residency Obligation, that will especially increase the risk of concerns, non-routine processing, and potentially RQ-related questions and document requests.
As others have noted, if the applicant is abroad so much during the preceding five years that he or she is in breach of the PR RO (in Canada less than 730 days during the preceding five years) prior to the day the oath is taken, that will automatically render the individual INELIGIBLE for citizenship.
Tangentially: while a typical PR Travel Document is single-use, in appropriate circumstances some PRs living abroad (typically this means a PR living abroad accompanying a Canadian-citizen-spouse
NOT PRs working abroad) are being issued a multi-use PR TD.
Meanwhile:
My only worry is that if I explain to them by email they then postpone his interview to months ahead and then ofcourse his oath would also be pushed ahead , yes he would then have his travel document by the time for the interview but it still means he will have to wait for his oath day which could be one month later or even three months later , due to his job overseas he can’t be away that long so he will travel back overseas again and ofcourse need to get another travel document again to come back for the oath , while his residency days in this second trip might be almost over , subsequently might affect the approval of his second travel document , that’s why it is crucial that we don’t delay this interview but how can you explain all this to cic???
While I do not fully grasp the situation, I get the gist of it, and the gist of it is that you are probably correct to be concerned about how all this is going to play out UNLESS he returns to attend the interview . . . and perhaps EVEN if he does manage to return and timely attend the interview. ESPECIALLY if, as your concern suggests, he has been outside Canada extensively in the last five years, so much so that unless he gets citizenship this year, or so, he will be running into a PR Residency Obligation compliance issue.
Situation probably risks non-routine processing and not taking the oath any time soon. It is possible that all will go well, especially if he can return in time to attend the interview, but there is a significant RISK of residence/presence related questions. Applicants who go abroad to work while the application is pending face an elevated risk of RQ-related non-routine processing, just because that indicates strong on-going ties abroad which invite concerns or questions about the accuracy of the presence calculation, inviting IRCC to take a closer look in order to verify the presence requirement was met.
Getting back to attend the interview could make the difference. Rescheduling tends to draw more attention.
He may be faced with some rather difficult personal decisions.
