1 MONTH OVERSTAY
Hello po! Need your opinion.
Magllodge na po kasi kami dapat ng student visa ni agent. Complete documents, good strong GTE. Basta everything is okay na sana, may isang issue lang po kami.
May overstay po ako sa other country. Approx. 1-2 months. Wala naman good reason other than gusto lang ako pag extend-in ng parents ko at the time. Scheduled ako umuwi ng November dapat, but suddenly they wanted me to extend and spend Christmas and New Year with them on said country.
My parents have lived there for approx. 20 years at the time, both have legal resident visas and working. But the country is a third world country, at sobrang lenient nila when it comes to laws. To the point na, wala talagang kaso kung mag overstay ka. Wala sila paki. I attached a screenshot of kung gaano ka lenient 
During that same trip kung saan i overstayed, it's also the same time na inapply na ko ng parents ko for the same resident visa that they have. So ang sinasabi nila ngayon (other than wala naman talaga kaso dun if you overstay), is during the time na lumagpas na yung 3 months (meaning overstayed na ko), we had already processed the application for the resident visa. And, according to parents, as long as may running application ka na for that, ok na yun. We only held on to a receipt of the application to present as needed. However, I have no proof of that receipt kasi five years ago na yun. Also cant find proof na pwede ngang receipt lang muna. But, honestly, the country's laws are so inconsistent po talaga. And sobrang walang maayos na structure even til now.
During the overstay, nagrant din ako ng exit visa, kasi nga expired na yung visa na ginamit para pumasok ng country. Then 4 months after, nasa pinas na ko, nagrant yung residency permit/visa ko.
Ang sinasabi ni agent is ideclare nalang namin yung trip, and gawa na lang ako ng letter explaining the whole situation. Considering na nakakuha naman ako ng exit visa after i overstayed, a residency visa 4 months after, and then successfully renewed said visa recently, thats enough to prove na wala naman talaga kaso sa bansa na yun yung pag overstay ko. Ni walang tatak sa passport or any record / stamp that says i overstayed. So best to declare daw and write a letter about it.
Ako naman, mejo kinakabahan, and considering the option na wag nalang ideclare yung period ng travel na yun. Kasi nga alam ko, red flag pag may overstay record. I dont even know if magiging considerate immi with my case. I really really want to go to au. But i also want to be honest with my application. Sobrang torn po ako.
Here's the full timeline of that trip para mas clear:

Questions:
Better po ba na ideclare na lang and just be honest. And write a letter about that whole trip? Madedetect pa rin ata ng immi yung travel na yun kahit di ko ideclare tama po ba?
Do you think ok lang naman yung situation ko, considering i was granted a residency sa country na yun after my overstay, and just recently successfully renewed? Also considering it was only 1 month? (agent wasnt too worried din, but syempre also not promising anything)
Anyone po ba had an experience / knows someone na may overstay record pero nakapasok pa in au?
Thank you so much po. Need as much opinion as i can get kasi maglodge na kami next week. Enrolled na ko sa school and everything. Ito na lang po talaga huhu. Thank you!
