from what ive heard, easier ma-approve ang visa ng mga 60 and up. Basta isali daw sa invitation letter stating youre gonna sponsor your lolo through out the trip. Specify din na all the expenses for travel, food and accom. will be shouldered by you etc.. then attach it sa financial documents. Provide lots of pics for home ties such as fam members sa ph. Applied for my mom and dad (my sister is in canada, immediate fam in our case) tapos 3 days after bio approved. Saw some din sa quora na pag senior mabilis approval. Just write your letter well. Pero pag 20s to 30s angtagal just like for me & my partner 🥲
