oh singaore yes been there and I only use a link to do the arrival card it's insane to download a app just to do arrival card...downloading the app probably take longer time den filling up the form
The arrival card starts 1st of May u can only filled the form 72hrs-0hrs before arrival.....it takes 5mins to fill the form I don't understand what time wasting u talking about just take it as learning something new a lot of countries already start using arrival cards
U said u have a extension with multiple re entry permit good till Nov 2025...u shd be ok check your passport again....if it's not there it means your extension is no longer valid but u still can enter thailand with other methods like visa exempt if u are in one of the countries listed
Just share my experience....I renew my passport online and collected my passport in the embassy in bkk get a letter fron your embassy stating your renewal and bring the letter and both passport to the immigration office to move your extensions and re entry permit to the new passport....
90days of validity of the visa to enter thailand and get stamp of 90days of stay when u enter...u can get a re entry permit for not losing that stamp when u go out of thailand but no extra days will be added when u come back to thailand again
