@acbien The additional documents needed are the new requirements for RSEA stated in MSA booklet 2017 defined below.
<i class="Italic"><b class="Bold">Secondary Documents (either 2 OR 3)</b>
2.1 Income Tax Return Acknowledgement or Receipt;
2.2 Social Security Insurance/ Superfund/ Provident Fund/ Retirement
Contribution Statement Reports.
<b class="Bold">OR</b>
3.1 Work Permit/ Residence Permit;
3.2 Official Contract Document from the Ministry of Labour etc..
(indicating your wage, title and employer’s name).
<b class="Bold">Note: 2.1 and 2.2 OR 3.1 and 3.2 must cover the entire employment
period and indicate your employer’s name</i></b>
Meaning, Tax declaration is item 2.1 and SSS contribution is item 2.2 and you must submit these 2 documents for the entire employment period.
You can also choose 3.1 and 3.2 if you have these documents.
In my opinion, if hindi ka talaga mka provide sa mga required additional documents, I think they will assess your employment claims based sa mga documents that you submitted.
