Temporary Residence Card (TRC) is available now for foreigners who are parents, spouses and children of Vietnamese citizens.
Actually I intend to apply for this when my work related TRC ends in this December but should go out of country and stay 2-3 weeks until they forward the TRC when ready to my embassy outside Viet Nam. So I applied and just got a 5 years VEC which also need an exit and re entry.
It is good if you can get a TRC for 3 years which avoid the hassle of 90 days extension.
Here is the documents needed for a TRC:
1. Application form ( NA8)
2. Sponsoring document(NA7)
3. 2x3cm photo which you can take inside immigration office studio for 30.000 VND when you go to purchase the forms set. (Yes, you should buy it from 196 Nguyen Thi Minh Khai, Q.1, HCMC, Vietnam which includes the full forms and application file)
4. Residence document from your registered police station house officer.
5. ID card and copies of your Vietnamese spouse/parent/children who is the sponsor
6. Original and copies of your Passport
