Quick question about 864 vs 864-EZ?

[rammstein 12]

I (petitioner) and my wife (beneficiary) are preparing ourselves by looking at forms that we might need to fill and submit to the NVC. In 2017, I was partly in the UK and partly in the US (7 months and 5 months, respectively), so I have two sources of income -- UK (not on W2) and the US (on W2) - have pay-stubs for both of them. I filed my taxes showing both the incomes and already have the 2017-return-transcript downloaded (yup, filed it in March).

Question - Since my UK income is not "documented using the IRS Form W-2", can I still file 864-EZ? I do have the UK pay stubs with me not only for 2017 but also for the 2015, 2016 along with irs-return-transcripts for all those years.

You will need to use the I-864.
