Whoa! Let's start this again from the top.
This question, or a version of this question, has been on form 2555 since 1981 that I know of, long before ACA was a twinkle in Obama's eye.
If the wife filed a 2018 return, then it is likely that, correctly, they are filing for the 'bona fide' resident option for the 2019 tax year. Bona fide residence indicates a permanent residence abroad for the tax year which is the purpose (IMO) for the question. For example, a person may stay in foreign country A for 5 months on a tourist visa, go to foreign country B for 4 months on a tourist visa, then on the foreign country C for 3 months on a tourist visa, all the while working remotely for a company in foreign country D for the entire year. Since they had no permanent residence in any of the countries or any tax obligation to those countries, they would not be allowed the FEIE on a bona fide residence basis. Bona fide residence allows the person to avoid the 330 day requirement of physical presence. Someone working and permanently resident in some Middle Eastern countries, for example, may have no local tax obligation but may meet the permanent residence requirement therefore allowing the FEIE.
TIGTA have issued several reports concerning people filing 2555 claiming FEIE, but are doing so fraudulently or incorrectly by not qualifying for the required residence. I forget which report it is, but here are 2 from the last 10 years:
https://www.treasury.gov/tigta/auditreports/2010reports/201040091fr.htmlhttps://www.treasury.gov/tigta/auditreports/2013reports/201330112fr.pdfWhen I first came to the UK it was on a one year work permit which could be extended after one year. At that time, the Frank Hirth tax people would put 'N/A' as a response to this question (as noted in the top line instructions for bona fide residence). As for an FLR visa (30 months?), it does have a time period, but that period can be transitioned to a further visa and ultimately ILR, so a
time limited non-residence visa abroad, as in the example of the transient worker in paragraph 3 above, doesn't come into consideration. (IMO)
I do agree there is no need to readdress a past filing to correct a response if the permanent residence requirements were met for that tax year.
In short, there may be a correct answer, but for someone on continuing FLR (IMO) the answer one way or the other (yes, no, N/A) may not really matter.
Welcome to IRS form filling ambiguous questions.
